Asteroids and CometsAsteroids are rocky bodies that orbit the solar system. Asteroids vary in sized and their movement is based on their revolution around the sun.
Comets are made up of ice, methane, ammonia gas, and dust. Comets also have a tail that only emerges when it is closer to the sun during orbit. Also comets tails are always pointing away from the sun. Comets have a long narrow elliptical orbit. |
