Document Summary

Sun & moons and rings (very similar) Asteroids, comets (similar to asteroids but have more ice), meteoroids (small asteroids- pebble size) Jupiter is the largest planet in the solar system. Very large: roughly 1000x the mass of all the planets. The sun is mostly hydrogen & helium gas. The 8 planets are very different from each other. Terrestrial planets: relatively small rocky planets & close to the sun (ex. Gas giants: mostly hydrogen gas and liquid- has a lot of moons. Ice giants: mostly hydrogen gas and liquid comb of water, methane, and ammonia (not actually made of ice, but these things could become ice depending on temperature) No interiors directly sampled theorized from remote measurements (the earth and the moon are the only two objects that have had this happen- size monitors) The other planets interiors are knows/theorized by looking at their moons and analyzing their orbits. The orbits give us clues about how their interior is like.
