Document Summary
4 rocky planets (mercury, venus, earth/moon, mars) 1 kuiper belt, containing > 10^9 objects with size > 1 km. 1 asteroid belt, 10^6 objects with size > 1km. 4 planetary rings (jupiter, saturn, uranus, neptune. Planet orbits are coplanar (inclinations are small. Sense of orbital motion is the same for all planets (none go backwards) Angular momentum of sun is small compared to angular momentum of planets (the faster you spin, the more angular momentum) Planets rotate (generally) in same sense as they orbit, excluding venus and uranus. Rocky planets lie closer to the sun than giant planets. Liquid carved channels on mars"s surface and splatter imprints around craters, water underneath surface. Moons: phoebe, hyperion (half density of water), enceladus (internal heat, cryovolcanism) Main asteroid belt between jupiter and mars. Asteroids inside of the main belt ring are ones that make contact w/ rocky planet surfaces.
