Click HERE for Q.No.51-100

101) Which type of star is maintained by the pressure of an electron gas?
(a) Main Sequence Star
(b) White Dwarf
(c) Neutron Star
(d) Black Hole
Answer: (b)
White dwarfs are stars supported by pressure of degenerate electron gas. i.e. in their interiors thermal energy kT is much smaller then Fermi energy Ep. We shall derive the equations of structure of white dwarfs, sometimes called degenerate dwarfs, in the limiting case when their thermal pressure may be neglected, but the degenerate electron gas may be either non-relativistic. somewhat relativistic. or ultra-relativistic.

102) Which of the following first hypothesized that the Earth orbited the sun?
(a) Alexander the Great
(b) Copernicus
(c) Socrates
(d) Tycho Brahe
Answer: (b)
Nicolaus Copernicus was a Renaissance mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at the center of the universe.

103) The LAST manned moon flight was made in what year?
(a) 1971 (b) 1972
(c) 1973 (d) 1974
Answer: (b)
The last manned landing Apollo 17 on the Moon to date, which took place on December 11, 1972, was made by Commander Eugene Cernan and lunar module pilot Harrison Schmitt who was also the first scientist on the Moon.

104) A planet is said to be at aphelion when it is:
(a) closest to the sun
(b) farthest from the sun
(c) at it’s highest point above the ecliptic
(d) at it’s lowest point below the ecliptic
Answer: (b)

105) The word Albedo refers to which of the following?
(a) The wobbling motion of a planet
(b) The amount of light a planet reflects
(c) The phase changes of a planet
(d) The brightness of a star
Answer: (b)
Albedo is a measure of the reflectivity of a surface. The albedo effect when applied to the Earth is a measure of how much of the Sun’s energy is reflected back into space. Overall, the Earth’s albedo has a cooling effect. (The term ‘albedo’ is derived from the Latin for ‘whiteness’).

106) A pulsar is actually a:
(a) black hole
(b) white dwarf
(c) red giant
(d) neutron star
Answer: (d)

107) Astronomers use Cepheid’s principally as measures of what? Is it:
(a) size
(b) speed
(c) chemical composition
(d) distance
Answer: (d)

108) Where are most asteroids located? Is it between:
(a) Jupiter and Saturn
(b) Mars and Venus
(c) Earth and Mars
(d) Mars and Jupiter
Answer: (d)

109) The precession of the Earth refers to the:
(a) change from night to day.
(b) Earth’s motion around the sun.
(c) change in orientation of the Earth’s axis.
(d) effect of the moon on the Earth’s orbit.
Answer: (c)
Precession is the change in orientation of the Earth’s rotational axis. The precession cycle takes about 19,000 – 23,000 years. Precession is caused by two factors: a wobble of the Earth’s axis and a turning around of the elliptical orbit of the Earth itself (Thomas, 2002). Obliquity affected the tilt of the Earth’s axis, precession affects the direction of the Earth’s axis. The change in the axis location changes the dates of perihelion (closest distance from sun) and aphelion (farthest distance from sun), and this increases the seasonal contrast in one hemisphere while decreasing it in the other hemisphere ( Kaufman, 2002). currently, the Earth is closest to the sun in the northern hemisphere winter, which makes the winters there less severe (Thomas, 2002). Another consequence of precession is a shift in the celestial poles. 5000 years ago the North Star was Thuban in the constellation Draco. Currently the North Star is Polaris in the constellation Ursa Minor.

110) The Magellanic cloud is a:
(a) nebula
(b) galaxy

111) The comet known as Halley’s Comet has an average period of:
(a) 56 years
(b) 66 years
(c) 76 years
(d) 86 years

115) What is the motion called when a planet seems to be moving westward in the sky?
(a) Retrograde
(b) Parallax
(c) Opcentric

Answer: (b)

127) A blue shift means a Doppler shift of light from a(an)
(a) receding star.
(b) blue star.
(c) approaching star.
(d) fixed star.
Answer: (c)
In the Doppler effect for visible light, the frequency is shifted toward the blue end of the spectrum when the light source (such as a star) is approaching.

128) The first and largest asteroid discovered was:
(a) Pallas.
(b) Juno.
(c) Ceres.
(d) Trojan.
Answer: (c)

129) The Crab Nebula consists of the remnants of a supernova which was observed by:
(a) Brahe in 1572.
(b) Kepler and Galileo in 1604.
(c) the Chinese in 1054 A.D.
(d) several ancient civilizations in 236 B.C.
Answer: (c)
The Crab Nebula, the result of a supernova noted by Earth-bound chroniclers in 1054 A.D., is filled with mysterious filaments that are are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion. The Crab Nebula spans about 10 light-years. In the nebula’s very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second.

130) The atmosphere of Venus contains mostly
(a) oxygen
(b) carbon dioxide
(c) nitrogen
(d) water
Answer: (b)
The atmosphere of Venus is composed of about 96% carbon dioxide, with most … various other corrosive compounds, and the atmosphere contains little water.

131) On the celestial sphere, the annual path of the Sun is called
(a) the eclipse path.
(b) ecliptic.
(c) diurnal.
(d) solstice.
Answer: (b)
The ecliptic is an imaginary line on the sky that marks the annual path of the sun. It is the projection of Earth’s orbit onto the celestial sphere.

132) The angular distance between a planet and the Sun, as viewed from the Earth, is called
(a) angle of inclination.
(b) elongation.
(c) latitude.
(d) opposition.
Answer: (b)
Elongation is the angular distance between the sun, and another object such a moon or a planet as seen from earth. There are several special names for these angular distances. The different names of these angles depend on the status, inferior or superior, of the planet. The planets closer to the sun than the earth are called inferior planets. The planets farther away from the sun than earth are called superior planets.
Elongation is measured from earth as the angle between the sun and the planet. Sometimes the apparent relative position of a planet in relation to the sun is called the aspect, or configuration, of a planet.

133) Which of the following has the highest density?
(a) Earth
(b) Venus
(c) Mars
(d) Jupiter
Answer: (a)
Earth has the highest density of any planet in the Solar System, at 5.514 g/cm3. This is considered the standard by which other planet’s densities are measured. In addition, the combination of Earth’s size, mass and density also results in a surface gravity of 9.8 m/s². This is also used as a the standard (one g) when measuring the surface gravity of other planets.

134) Which of the following planets is NOT a terrestrial planet?
(a) Earth
(b) Jupiter
(c) Mars
(d) Mercury
Answer: (b)
The term terrestrial planet is derived from the Latin “Terra” (i.e. Earth). Terrestrial planets are therefore those that are “Earth-like”, meaning they are similar in structure and composition to planet Earth. All those planets found within the Inner Solar System – Mercury, Venus, Earth and Mars – are examples of terrestrial planets. Each are composed primarily of silicate rock and metal, which is differentiated between a dense, metallic core and a silicate mantle.

135) Why do we see lunar eclipses much more often than solar eclipses?
(a) Lunar eclipses occur more often than solar eclipses.
(b) Lunar eclipses last longer than solar eclipses.
(c) The lunar eclipse is visible to much more of the Earth than a solar eclipse.
(d) The moon is closer to the Earth than the sun.
Answer: (c)
Lunar and solar eclipses occur with about equal frequency. Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, we are more likely to see a lunar eclipse than a solar eclipse.

136) A star like object with a very large red shift is a
(a) Neutron star.
(b) Nova.
(c) Quasar.
(d) Supernova.
Answer: (c)
Quasars: In the 1930’s, Edwin Hubble discovered that all galaxies have a positive redshift. In other words, all galaxies were receding from the Milky Way.

(c) caused by the reflection of polar snow.
(d) caused by precession.
Answer: (b)
The Van Allen belts are a collection of charged particles, gathered in place by Earth’s magnetic field. They can wax and wane in response to incoming energy from the sun, sometimes swelling up enough to expose satellites in low-Earth orbit to damaging radiation.

139) A coordinate system based on the ecliptic system is especially useful for the studies of
(a) Planets
(b) Stars
(c) The Milky Way
(d) Galaxies
Answer: (a)

140) The mean distance of the earth from the sun in astronomical units is:
(a) 3.7 (b) 10
(c) 1 (d) 101
Answer: (c)
In astronomy, an astronomical unit is defined as the average distance from the Sun to the Earth, or about 150 million kilometers (93 million miles). You can abbreviate astronomical unit as AU.
Since the distances in astronomy are so vast, astronomers use this measurement to bring the size of numbers down.
For example, Earth is 1 au from the Sun, and Mars is 1.523 AU. That’s much easier than saying that Mars is 227,939,000 km away from the Sun.

141) What process produces a star’s energy?
(a) hydrogen and oxygen combustion
(b) nuclear fusion
(c) neutron beta decay
(d) nuclear fission
Answer: (b)
The enormous luminous energy of the stars comes from nuclear fusion processes in their centers. Depending upon the age and mass of a star, the energy may come from proton-proton fusion, helium fusion, or the carbon cycle.

142) What is the most distant object in the sky that the human eye can see without optical instruments?
(a) The Horsehead Nebula
(b) The Andromeda Galaxy
(c) The Sagittarius Constellation
(d) The Aurora Borealis
Answer: (b)
The Andromeda Galaxy (M31) is the closest large galaxy to the Milky Way and is one of a few galaxies that can be seen unaided from the Earth. In approximately 4.5 billion years the Andromeda Galaxy and the Milky Way are expected to collide and the result will be a giant elliptical galaxy. Andromeda is accompanied by 14 dwarf galaxies, including M32, M110, and possibly M33 (The Triangulum Galaxy).

143) Which civilization developed and implemented the first solar calendar?
(a) Babylonian
(b) Greek
(c) Egyptian
(d) Aztec
Answer: (c)
A solar calendar is a calendar whose dates indicate the position of the earth on its revolution around the sun and is based on the seasonal year of approximately 365 1/4 days, the time it takes the Earth to revolve once around the Sun. The Egyptians appear to have been the first to develop a solar calendar, using as a fixed point the annual sunrise reappearance of the Dog Star — Sirius, or Sothis — in the eastern sky, which coincided with the annual flooding of the Nile River. They constructed a calendar of 365 days, consisting of 12 months of 30 days each, with 5 days added at the year’s end. The Egyptians’ failure to account for the extra fraction of a day, however, caused their calendar to drift gradually into error.

144) What is the HOTTEST region of the sun?
(a) The core
(b) The photosphere
(c) The chromospheres
(d) The corona
Answer: (d)
The corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere) The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more, up to a few million K. The corona cannot be seen with the naked eye except during a total solar eclipse, or with the use of a coronagraph. The corona does not have an upper limit.
A study published in 2012 in Nature Communications by researchers at Northumbria University found a possible mechanism that causes some stars to have a corona that is almost 200 times hotter than their photosphere (the star’s surface).

145) The same side of the moon always faces the Earth because:
(a) the moon is not rotating about its axis.
(b) the moon’s motion was fixed at its creation by the laws of inertia.
(c) tidal forces keep the moon’s rotation and orbiting motion in sync with each other.
(d) the moon’s magnetic poles keep aligned with the Earth’s magnetic field.
Answer: (b)

146) The resolving power of a telescope depends on the:
(a) focal ratio
(b) diameter of the objective
(c) magnification
(d) focal length
Answer: (b)
The resolving power of a telescope depends on the diameter of the telescope’s light-gathering apparatus, or objective. In a refracting telescope, the objective lens is the first lens the light passes through. In a reflecting telescope, the objective is the telescope’s primary mirror. In a Schmidt-Cassegrain telescope, the objective is also the primary mirror. As the diameter of the telescope’s objective increases, the resolving power increases.

147) On a clear, dark, moonless night, approximately how many stars can be seen with the naked eye?
(a) 300 (b) 1,000
(c) 3,000 (d) 10,000
Answer: (c)
On any clear dark moonless night a person can see about 3000 stars of our galaxy without the aid of a telescope

148) The study of the origin and evolution of the universe is known as:
(a) Tomography
(b) cystoscopy
(c) cryology
(d) cosmology
Answer: (d)
Cosmology is the branch of astronomy involving the origin and evolution of the universe, from the Big Bang to today and on into the future. According to NASA, the definition of cosmology is “the scientific study of the large scale properties of the universe as a whole.”

149) According to Kepler’s Laws, all orbits of the planets are:
(a) ellipses
(b) parabolas
(c) hyperbolas
(d) square
Answer: (a)
Johannes Kepler, working with data painstakingly collected by Tycho Brahe without the aid of a telescope, developed three laws which described the motion of the planets across the sky.
1. The Law of Orbits: All planets move in elliptical orbits, with the sun at one focus.
2. The Law of Areas: A line that connects a planet to the sun sweeps out equal areas in equal times.
3. The Law of Periods: The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit.
Kepler’s laws were derived for orbits around the sun, but they apply to satellite orbits as well.

The innermost of these, Phobos, is about 7 mi (11 km) in diameter and orbits the planet with a period far less than Mars’s period of rotation (7 hr 39 min), causing it to rise in the west and set in the east. The outer satellite, Deimos, is about 4 mi (6 km) in diameter.

58) All stars are of the same color
(False)

59) Our galaxy milky way is shaped like a large thick concave lens with a large central bulge (CSS 2002)
(True)

60) The coldest planet of the solar system is: (CSS 2000)
(a) Earth
(b) Venus
(c) Neptune d) Pluto
(e) None of these
Answer: (c)
In the past, the title for “most frigid body” went to Pluto, as it was the farthest then-designated planet from the Sun. However, due to the IAU’s decision in 2006 to reclassify Pluto as a “dwarf planet”, the title has since passed to Neptune. As the eight planet from our Sun, it is now the outermost planet in the Solar System, and hence the coldest.

61) Venus is the smallest planet of the solar system. (CSS 1999)
(False)

Answer: (b)
The moons of Mars are Phobos and Deimos. Both moons were discovered in 1877 by Asaph Hall Asaph Hall was about to give up his frustrating search for a Martian moon one August night in 1877, but his wife Angelina urged him on. He discovered Deimos the next night, and Phobos six nights after that. Ninety-four years later, NASA’s Mariner 9 spacecraft got a much better look at the two moons from its orbit around Mars. The dominant feature on Phobos, it found, was a crater 10 km (6 miles) wide — nearly half the width of the moon itself. It was given Angelina’s maiden name: Stickney.

(a) Size of the earth in relation to that of moon
(b) Orbit of moon around earth
(c) Direction of rotation of earth around sun
(d) Area of the sun covered by the moon
(e) None of these
Answer: (b)

75) Where do most of Asteroids lie? (CSS-2009)
(a) In asteroid belt between the orbits of Mars and Jupiter
(b) In asteroid belt between the orbits of Mars and Venus
(c) In asteroid belt between the orbits of Jupiter and Venus
(d) Everywhere in the sky
(e) None of these
Answer: (a)
Most asteroids lie in a vast ring between the orbits of Mars and Jupiter. This main asteroid belt holds more than 200 asteroids larger than 60 miles (100 kilometers) in diameter. Scientists estimate the asteroid belt also contains more than 750,000 asteroids larger than three-fifths of a mile (1 km) in diameter and millions of smaller ones. Not everything in the main belt is an asteroid — for instance, comets have recently been discovered there, and Ceres, once thought of only as an asteroid, is now also considered a dwarf planet.

76) The largest circular storm in our solar system is on the surface of which of the following planets?
(a) Jupiter
(b) Venus
(c) Uranus
(d) Earth
Answer: (a)
Jupiter boasts the largest storm in the Solar System . It is called the Great Red Spot and has been observed for hundreds of years that kind of storm is dwarfed by the Great Red Spot, a gigantic storm in Jupiter. There, gigantic means twice as wide as Earth. Today, scientists know the Great Red Spot is there and it’s been there for a while, but they still struggle to learn what causes its swirl of reddish hues.

77) The biggest asteroid known is:
(a) Vesta
(b) Icarus
(c) Ceres
(d) Eros
Answer: (c)
Ceres, a dwarf planet and the largest asteroid in the solar system yet known. Discovered in 1801 and first thought to be a planet and then an asteroid, we now call Ceres a dwarf planet. Gravitational forces from Jupiter billions of years ago prevented it from becoming a full-fledged planet. But Ceres has more in common with Earth and Mars than its rocky neighbors in the main asteroid belt. There may even be water ice buried under Ceres’ crust.

78) Rounded to the nearest day, the Mercurian year is equal to:
(a) 111 days
(b) 87.97 days
(c) 50 days
(d) 25 days
Answer: (b)
Mercurian Year: A year on Mercury takes 87.97 Earth days; it takes 87.97 Earth days for Mercury to orbit the sun once

79) One of the largest volcanoes in our solar system-if not the largest-is named Olympus Mons. This volcano is located on:
(a) Jupiter’s moon Callisto
(b) Venus
(c) Saturn’s moon Titan
(d) Mars
Answer: (d)
Olympus Mons is the largest volcano in the solar system. The massive Martian mountain towers high above the surrounding plains of the red planet, and may be biding its time until the next eruption. Olympus Mons rises three times higher than Earth’s highest mountain, Mount Everest, whose peak is 5.5 miles above sea level.

80) One Jupiter day is equal to which of the following?
(a) 30 hrs 40 min
(b) 9 hrs 50 min
(c) 3 hrs 20 min
(d) 52 hrs 10 min
Answer: (b)

81) The time interval between two successive occurrences of a specific type of alignment of a planet (or the moon) with the sun and the earth is referred to as:
(a) a conjunction
(b) an opposition
(c) a sidereal period
(d) a synodic period.
Answer: (d)
Synodic period , in astronomy, length of time during which a body in the solar system makes one orbit of the sun relative to the earth, i.e. The synodic period of the moon, which is called the lunar month, or lunation, is 291/2 days long; it is longer than the sidereal month.

83) The sunspot cycle is:
(a) 3 years
(b) 11 years
(c) 26 years
(d) 49 years
Answer: (b)

The amount of magnetic flux that rises up to the Sun’s surface varies with time in a cycle called the solar cycle. This cycle lasts 11 years on average. This cycle is sometimes referred to as the sunspot cycle.

84) The Hertzsprung-Russel Diagram of stars DIRECTLY compares what TWO of the following properties of stars?
(a) size
(b) temperature
(c) luminosity
(d) Both b & c
Answer: (d)
One of the most useful and powerful plots in astrophysics is the Hertzsprung-Russell diagram (hereafter called the H-R diagram). It originated in 1911 when the Danish astronomer, Ejnar Hertzsprung, plotted the absolute magnitude of stars against their color (hence effective temperature). Independently in 1913 the American astronomer Henry Norris Russell used spectral class against absolute magnitude. Their resultant plots showed that the relationship between temperature and luminosity of a star was not random but instead appeared to fall into distinct groups.

The majority of stars, including our Sun, are found along a region called the Main Sequence. Main Sequence stars vary widely in effective temperature but the hotter they are, the more luminous they are, hence the main sequence tends to follow a band going from the bottom right of the diagram to the top left. These stars are fusing hydrogen to helium in their cores. Stars spend the bulk of their existence as main sequence stars. Other major groups of stars found on the H-R diagram are the giants and supergiants; luminous stars that have evolved off the main sequence, and the white dwarfs. Whilst each of these types is discussed in detail in later pages we can use their positions on the H-R diagram to infer some of their properties.

85) The Andromeda Galaxy is which of the following types of galaxies?
(a) elliptical
(b) spiral
(c) barred-spiral
(d) irregular
Answer: (b)
The Andromeda Galaxy also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kilo parsecs (2.5 million light-years) from Earth

86) About how many light years across is the Milky Way? Is it:
(a) 1,000
(b) 10,000
(c) 100,000
(d) 1,000,000
Answer: (c)
100 000 light years across
A light-year is precisely equal to a whole number of meters, namely 9460730472580800 m or approximately 9.46073 1015 m. That’s the distance traveled by light in a vacuum, at a speed of 299792458 m/s, during a “scientific year” of 31557600 s. All these numbers are exact… In particular, “Einstein’s Constant” is exactly c = 299792458 m/s, because of the latest definition of the meter, officially adopted in 1983.

87) Who was the first man to classify stars according to their brightness. Was it:
(a) Aristarchus
(b) Pythagoras
(c) Copernicus
(d) Hipparchus
Answer: (d)
The first person to classify stars by their apparent magnitude (brightness) was Hipparchus in about 130 BC. He divided the stars into classes based on how bright they appeared in the night sky. The brightest stars were classified as magnitude 1, those that were just visible to the naked eye as magnitude 6. In practice the intensity of a magnitude 1 star is 100 times that of a magnitude 6 star, so the 5 magnitude steps correspond to a multiple of 100. For a geometric series of magnitudes each magnitude must be a times the intensity of the previous one with a5 – 100. This means that going up one magnitude increases the intensity by a factor of a = 2.51. So magnitude 3 is 2.51 times as intense as magnitude 4 and so on.

88) For what reason was the Schmidt telescope specially built? Was it to serve as:
(a) a sky camera
(b) a radio telescope
(c) an optical telescope
(d) a solar telescope
Answer: (a)

A Schmidt camera, also referred to as the Schmidt telescope, is a catadioptric astrophotographic telescope designed to provide wide fields of view with limited aberrations. The design was invented by Bernhard Schmidt in 1930.

89) The greatest distance of a planet from the sun is called what? Is it the planet’s:
(a) aphelion
(b) perihelion
(c) helix
(d) eccentricity
Answer: (a)
The closest point to the Sun in a planet’s orbit is called perihelion. The furthest point is called aphelion

90) How is the atmospheric pressure of Mars as compared to the atmospheric pressure of the earth? Is it:
(a) about the same as the earth’s
(b) about 100 times as great as the earth’s
(c) about 1/200th that of the earth’s
(d) half as much as that of the earth’s
Answer: (c)
The atmosphere and (probably) the interior of Mars differ substantially from that of the Earth. The atmosphere is much less dense and of different composition, and it is unlikely that the core is molten.
The atmosphere has a pressure at the surface that is only 1/200 that of Earth. The primary component of the atmosphere is carbon dioxide (95%), with the remainder mostly nitrogen. Seasonal heating drives strong winds that can reach 100 mph or more, stirring up large dust storms. Clouds form in the atmosphere, but liquid water cannot exist at the ambient pressure and temperature of the Martian surface: water goes directly between solid and vapor phases without becoming liquid.

91) A typical galaxy, such as our Milky Way galaxy, contains how many billion stars? Is it approximately:
(a) 10 billion
(b) 40 billion
(c) 400 billion
(d) 800 billion
Answer: (c)
According to astronomers, our Milky Way is an average-sized barred spiral galaxy measuring up to 120,000 light-years across. Our Sun is located about 27,000 light-years from the galactic core in the Orion arm. Astronomers estimate that the Milky Way contains up to 400 billion stars of various sizes and brightness.
According to astronomers, there are probably more than 170 billion galaxies in the observable Universe, stretching out into a region of space 13.8 billion light-years away from us in all directions.

92) A comet’s tail points in which direction?
(a) toward the sun
(b) toward the earth
(c) behind the comet in its orbit
(d) away from the sun
Answer: (d)
Comet tails are expansions of the coma. Comet tails point away from the Sun, regardless of the direction in which the comet is traveling. Comets have two tails because escaping gas and dust are influenced by the Sun in slightly different ways, and the tails point in slightly different directions.

93) Spectral line splitting due to the influence of magnetic fields is called:
(a) Boltzmann Effect
(b) Zeeman Effect
(c) Planck Effect
(d) Zanstra’s Effect
Answer: (b)
The Zeeman effect is the splitting of a spectral line by a magnetic field. That is, if an atomic spectral line of 400 nm was considered under normal conditions, in a strong magnetic field, because of the Zeeman effect, the spectral line would be split to yield a more energetic line and a less energetic line, in addition to the original line at 400 nm.

99) The Magellanic Clouds are
(a) irregular galaxies
(b) spiral galaxies
(c) elliptical galaxies
(d) large clouds of gas and dust
Answer: (a)
The Magellanic Clouds are comprised of two irregular galaxies, the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC), which orbit the Milky Way once every 1,500 million years and each other once every 900 million years. Lying only about 200,000 light years away, they were the closest known galaxies to the Milky Way until recently, when the Sagittarius and Canis Major dwarf galaxies were discovered and found to be even closer.

100) According to Kepler’s Laws, the cube of the mean distance of a planet from the sun is proportional to the:
