Answer:
Comets and asteroid (including the meteoroids) are leftovers from the formation of our solar system 4.6 billion years ago.
Explanation:
- A comet is a fuzzy luminous big snowball composed of rock dust wrapped around a big ball of ice. They are icy objects
- An asteroid is a rocky or metallic object that orbits the sun. They are hard to see because they reflect little light.
- Comets are made from ice and dust not rock while asteroid is made up from rock. But comets can be similar to an asteroid because they both orbit the sun.
