Past the asteroid belt(composed of rocky asteroids) Composed of h, he, and h compounds. Most extreme seasons because of large axis tilt. Composed of he h and h compounds. Kuiper belt- icy objects the orbit the sun beyond neptune (pluto and eris included) All planetary motions are nearly circular and lie in the same plane. Most planets rotate in the same direction they orbit. Small and dense with rocky surfaces and metal cores. Are composed of h, he, and h compounds. Asteroids are rocky bodies that orbit the sun. Found in the asteroid belt between mars and jupiter. Comets are small objects that orbit the sun but are ice and rock.
