Answer 1

I think its 3)in orbit around the sun

i hope i helped even just a little :)

Answer 2

3) in orbit around the sun.

• The motions of comets and asteroids in our solar system are predictable because they are in orbit around the sun.
• Asteroids are rocky. They come from the inner solar system, where any ice would have been baked off by the sun long ago.
• Their orbits are fairly predictable. That means new comets can arrive in the inner solar system ,something we have no way of predicting ahead of time.
• Asteroid revolves around the Sun in elliptical orbits.
