Ans: The solar system is a family of celestial bodies including the Sun, eight planets, their moons, and other objects like asteroids and comets, all revolving around the Sun.
Q6. Why is the Sun important for us?
Ans: The Sun is important because it provides light and heat, supports life on Earth, and keeps all the planets in orbit due to its gravitational force.
Q7. What are planets?
Ans: Planets are large celestial bodies that revolve around a star (like the Sun) and do not have their own light.
Q8. Name all the eight planets in order from the Sun.
Ans: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
Q9. What is a satellite?

📖 Long Answer Questions
Q10. How is the Moon different from the Earth?
Ans: The Moon is much smaller than the Earth. It has no atmosphere, no water, and no life. The surface is covered with craters. In contrast, Earth has air, water, and supports life.
Q11. Explain the concept of a star and how the Sun qualifies as one.
Ans: A star is a massive celestial body that produces its own light and heat. The Sun is a star because it emits light and energy due to nuclear reactions in its core. It is the closest star to Earth.
Q12. Why is Earth called a unique planet?
Ans: Earth is called a unique planet because it supports life. It has water, oxygen, a suitable atmosphere, and the right distance from the Sun that makes it habitable.
Q13. What are asteroids and where are they found?
Ans: Asteroids are rocky objects that revolve around the Sun. They are mostly found between the orbits of Mars and Jupiter in the region known as the asteroid belt.
Q14. What is the difference between stars and planets?
Ans: Stars are luminous bodies that produce their own light, while planets are non-luminous and reflect the light of a star (like the Sun). Stars are very hot and far away, while planets are cooler and revolve around stars.
🔍 Higher Order Thinking Questions (HOTS)
Q15. If Earth moved closer to the Sun, what could happen?
Ans: If Earth moved closer to the Sun, temperatures would rise drastically, possibly making life difficult or even impossible due to extreme heat.
Q16. Why do we always see the same side of the Moon?
Ans: We always see the same side of the Moon because it takes the same amount of time to rotate on its axis as it does to revolve around the Earth — about 27 days.
Q17. How does the Sun control the solar system?
Ans: The Sun controls the solar system through its strong gravitational pull, which keeps all the planets, moons, asteroids, and comets in orbit around it.
