  10. Inner and Outer • Sim – rocky, mostly made of rock, solid core made of iron • Dif- gas giants, huge, mostly made of gases, seem to not have solid surfaces, mostly made up of hydrogen and helium, may have ice and rock at the core, ring system, many moons

  11. What else • Comet – mostly ice mixed with rocks and dust, moves in long narrow orbit • Asteroid – large chunks of rock or metal in space • Meteor – pieces of asteroid that make it into the earths atmosphere. These look like shooting stars • Meteorite – when a meteor reaches the earth’s surface it becomes a meteorite.
