Answer- Satellites and asteroids are the objects that are the members of solar system.
 
Question 12. Explain how you can locate the Pole Star with the help of Ursa Major.
Answer- To locate the Pole Star we should look towards the northern part of the sky and identify Ursa Major. We may look at the two stars at the end of Ursa Major. A straight line passing through these stars is
imagined and is extended towards the north direction. This line leads to a star which is not too bright. This is
the Pole Star.
 
Question 13. Do all the stars in the sky move? Explain.
Answer- No, no star moves in sky. They appear to move from east to west, because the Earth rotates from west to east about its axis.
 
Question 14. Why is distance between stars expressed in light years? What do you understand by the statement that a star is eight light years away from the earth?
Answer- The distance of stars is so large that it cannot be expressed in terms of kilometer. That is why very large distances are expressed in another unit known as light year. One light year is the distance travelled by light in one year. If the distance of a star is eight light years, it means that this distance is the distance travelled by light in eight years.
 
Question 15. The radius of Jupiter is 11 times the radius of Earth. Calculate the ratio of the volumes of Jupiter and the earth. How many earths can Jupiter accommodate?
Answer- If the radius of the Earth is r.
Then, radius of the Jupiter is 11r.
