(a) 1
(b) 2
(c) 5
(d) 14
Answer: (b)
Mars has two natural satellites, discovered by Asaph Hall in 1877. 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.

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.

82) Of the following four times, which one best represents the time it takes energy generated in the core of the sun to reach the surface of the sun and be radiated?
(a) Three minutes
(b) Thirty days
(c) One thousand years
(d) One million years
Answer: (d)

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.

94) Which of the following is true for ORION? Orion is:
(a) the brightest star in the sky
(b) a constellation

96) The most distant planet in the solar system is (CSS 1995)
(a) Mars
(b) Pluto
(c) Jupiter
(d) None of these
Answer: (d)
New Dwarf Planet In Our Solar System May Be The Farthest One Yet. Object V774104 was discovered in late October, 2015, and is one of the most distant objects ever detected in the solar system. It appears to be about half the size of Pluto, but with an orbit two to three times larger than Pluto’s. (Nov 12, 2015)

97) The 2.7 Kelvin cosmic background radiation is concentrated in the:
(a) radio wavelengths
(b) infrared
(c) visible
(d) ultraviolet
Answer: (a)

98) If you were watching a star collapsing to form a black hole, the light would disappear because it:
(a) is strongly red shifted
(b) is strongly blue shifted
(c) its color suddenly becomes black
(d) none of the above
Answer: (a)

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.

Atmosphere of the Moon might be electro statically levitated moon dust. These tiny particles are constantly leaping up and down off the surface of the Moon.

4) Who gave the first evidence of the Big- Bang theory?

(a) Edwin Hubble
(b) Albert Einstein
(c) S. Chandrasekhar
(d) Stephen Hawking
Answer: (a)
The Hubble Space Telescope was named after astronomer Edwin Powell Hubble (1889–1953), who made some of the most important discoveries in modern astronomy. Dr. Hubble determined that the farther a galaxy is from Earth, the faster it appears to move away. This notion of an “expanding” universe formed the basis of the Big Bang theory, which states that the universe began with an intense burst of energy at a single moment in time — and has been expanding ever since.

That means our Solar System has made around 18 complete circuits since it was formed around 4.5 billion years ago.

9): The planet having the largest diameter is

(a) Earth
(b) Jupiter
(c) Venus
(d) Uranus
Answer: (b)
Jupiter is composed primarily of gaseous and liquid matter. It is the largest of the four giant planets in the Solar System and hence its largest planet. It has a diameter of 142,984 km (88,846 mi) at its equator

10) The planet Mercury completes one rotation around the sun is (CSS 2010)

(a) 88 days
(b) 365 days
(c) 98 days
(d) 60 days
(e) None of these
Answer: (a)
A year on Mercury is just 88 days long. One solar day (the time from noon to noon on the planet’s surface) on Mercury lasts the equivalent of 176 Earth days while the sidereal day (the time for 1 rotation in relation to a fixed point) lasts 59 Earth days. Mercury is nearly tidally locked to the Sun and over time this has slowed the rotation of the planet to almost match its orbit around the Sun. Mercury also has the highest orbital eccentricity of all the planets with its distance from the Sun ranging from 46 to 70 million km.

11) The biggest planet in our solar system is (CSS 2013)

(a) Venus
(b) Pluto
(c) Jupiter
(d) None of these
Answer: (c)

(a) 90% Hydrogen, 10% Nitrogen
(b) 80%Nitrogen, 20% Hydrogen
(c) 60% Nitrogen, 40%inert gases
(d) None of these
Answer: (d)
The Apollo 17 mission deployed an instrument called the Lunar Atmospheric Composition Experiment (LACE) on the moon’s surface. It detected small amounts of a number of atoms and molecules including helium, argon, and possibly neon, ammonia, methane and carbon dioxide.

13) Which of the following explains the reason why there is no total eclipse of the sun? (CSS 2009)

(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: (d)
A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth’s surface.

14) The sun produces most of its energy by (CSS 2012)

(a) Nuclear fusion which involves converting “H” to “He”
(b) Nuclear fission involving the burning of uranium & plutonium
(c) Nuclear fission involving the combining of uranium and palladium
(d) None of these
Answer: (a)
Sun, like all stars, is able to create energy because it is essentially a massive fusion reaction.
The core of the Sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into molecules of helium (He) This is possible thanks to the extreme pressure and temperature that exists within the core, which are estimated to be the equivalent of 250 billion atmospheres (25.33 trillion KPa) and 15.7 million kelvin, respectively.

15) Although the mass of a man on moon remains same as on the earth he will (CSS 2012)

(a) Be much happier there
(b) Weigh one sixth as much
(c) Weigh twice as much
(d) None of these
Answer: (b)
The Moon’s gravity is one sixth of the Earth’s gravity. A 120 kg astronaut weighs 1200 N on Earth. On the Moon they would weigh only 200 N. The astronaut’s mass is 120kg wherever they are.

(a) A Blue giant
(b) A Yellow dwarf
(c) Supernova
(d) None of these
Answer: (b)
The sun is classified as a G-type main-sequence star, or G dwarf star, or more imprecisely, a yellow dwarf. Actually, the sun — like other G-type stars — is white, but appears yellow through Earth’s atmosphere. Stars generally get bigger as they grow older

20): Name the planet which revolve approximately 90 degree with its orbital plane_.

(a) Neptune
(b) Venus
(c) Uranus

(a) North to south
(b) South to north
(c) East to west
(d) West to east
Answer: (c)
Every day, the Sun, Moon, planets, and stars appear to rise in the east and set in the west. Actually, these celestial objects aren’t moving that fast, but Earth is. It spins on its axis from west to east approximately every 24 hours.
Because we are standing on Earth’s surface, we move along with it. To us, it appears as if everything in the sky is moving from east to west.

24): The body burning like a star and coming towards the earth

(a) Comet
(b) Meteor
(c) Ceres
(d) Satellites
Answer: (b)
Fleeting trails of light are called meteors or shooting stars and they are created by small particles, some no bigger than a grain of rice, as they are completely burned up high in the atmosphere: about 100 km (or 60 miles) above the Earth. They are over literally in the blink of an eye. Space debris is collectively termed meteoroids, those larger fragments that reach the ground are called meteorites. Very big meteoroids are also known as asteroids. If one collides with Earth it would cause a major catastrophe.

37) Orbital period of the planet Mercury around the sun is: (CSS 2009)

(a) 88 days
(b) 365 days
(c) 2 years
(d) 98 days
(e) None of these
Answer: (a)
Mercury has an orbital period of 88 days (87.969 to be exact), which means a single year is 88 Earth days – or the equivalent of about 0.241 Earth years. But here’s the thing. Because of Mercury’s slow rotation (once every 58.646 days) and its rapid orbital speed (47.362 km/s), one day on Mercury actually works out to 175.96 Earth days.
