- Asteroids are rocky debris of varying sizes orbiting the Sun.
- Most of the asteroids are small but some have diameter as large as 1000 km.
- The orbit of asteroids lies between orbits of Jupiter and Saturn.
Answer: Option D. -> 1 and 2 only
Answer: (d)Asteroids are rocky debris of varying sizes orbiting the Sun. They are generally small but some have a diameter of 1000 km.
