(a) 1 and 2 Only
(b) 2 and 3 Only
(c) 1 and 3 Only
(d) All are correctly matched
Correct Answer – (d) All are correctly matched
- Venus is called Earth’s twin because of its similar size, mass, and composition to Earth.
- Venus is the second planet from the sun in terms of distance.
- Venus is the brightest planet in the solar system, and is often visible in the night sky within a few hours of sunset or before sunrise therefore it is also called the “Morning star” or “Evening star”.
- Jupiter is the largest in the Solar System.
- It is the fifth planet from the Sun in terms of distance.
3. Hottest Planet in the Solar System is :
(a) Venus
(b) Mercury
(c) Mars
(d) Jupiter
Correct Answer – (a) Venus
- Venus is the hottest planet in our solar system.
- Venus has a thick atmosphere made up of greenhouse gasses like carbon dioxide which traps heat and creates a greenhouse effect.
- This greenhouse effect causes the rise in surface temperature of Venus to around 465°C (865°F).
4. Which among the following planets is called Red planet :
(a) Venus
(b) Mercury
(c) Mars
(d) Jupiter
Correct Answer – (c) Mars
- Mars is known as the red planet because it looks red from Earth.
- The reddish color comes from the high concentration of iron oxide in the rocks of the Martian surface.
- Phobos and Deimos are the two moons of Mars.
5. The Asteroid Belt is located between which among the following planets :
(a) Venus & Mercury
(b) Venus & Earth
(c) Mars & Earth

Which of the above assertions is/are true?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) None of the Above
Correct Answer – (c) Both 1 and 2
- Black holes are the combination of large mass and small size having high density.
- The center of the black hole is called the Singularity.
- A black hole exerts such massive gravitational force that its escape velocity is equal or more than speed of light.
10. Consider the following statements about Galaxy :
1. We live in the galaxy called the Milky Way.
2. It is a spiral galaxy.
Which of the above assertions is/are true?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) None of the Above
Correct Answer – (c) Both 1 and 2
- Galaxies can be of various kinds like elliptical, spirals etc.
- We live in the galaxy called the Milky Way.
- It is a spiral galaxy.
- The Andromeda Galaxy is the closest large galaxy to the Milky Way which can even be seen from earth with naked eyes.
11. Consider the following statements about Stars:
1. Stars shine because nuclear fission occurs in their core.
2. Proxima centauri is the closest star to Earth after the sun.
Which of the above assertions is/are true?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) None of the Above
Correct Answer – (b) 2 only
- Stars shine because nuclear fusion occurs in their core.
- Nuclear fusion converts lighter elements into heavier ones and in the process releases tremendous amounts of energy.
- Proxima centaury is the closest star to Earth after the Sun. It is about 4.3 light-years away from Earth.
12. Consider the following statements about about Sun:
1. The Sun is not a solid object but rather a big ball.
2. The Sun is mostly made of Hydrogen and Helium.
Which of the above assertions is/are true?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) None of the Above
Correct Answer – (c) Both 1 and 2
- Both the statements are true.
- The Sun is not a solid object but rather a big ball.
- It is mostly made of Hydrogen and Helium.
13. Consider the following statements::
1. Comets can have a long tail-like structure attached to them.
2. Meteors burn up in the atmosphere and can never reach the earth surface.
Which of the above assertions is/are true?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) None of the Above
Correct Answer – (a) 1 only
- Comets are rocky and icy objects that move in long, highly elliptical orbits around the Sun.
- When they get closer to the Sun, they warm up, causing the ice in the comets to vaporize and form long “tails”.
- A Meteor is an object from outer space that enters Earth’s atmosphere, but does not land on Earth as it gets burned in the atmosphere . However, some meteors are large enough to reach the earth surface. Those are called Meteorites.
14. Which among the following planets is called Blue Planet ?
(a) Venus
(b) Mercury
(c) Mars
(d) Earth
Correct Answer – (d) Earth
- Earth is called the “Blue Planet” due to the abundant water on its surface.
- Two-thirds of the earth’s surface is covered with water.
13. Parsec is used to measure which among the following ?
(a) Density of stars
(b) Astronomical distances
(c) Brightness of stars
(d) Orbital velocity of planets
Correct Answer – (b) Astronomical distances
- A parsec (pc) is a unit of length used to measure the Astronomical distances outside the solar system.
- It’s the largest unit of distance used in astronomy.
- One parsec is approximately equal to 3.26 light-years.
