Document Summary
1 solar system debris and formation: chapters 14 and 15 of your textbook, exercises: do all review and discussion and all conceptual self-test. Most under 300km across, orbit mostly in asteroid belt 2. 1 to 3. 3 au (between orbit of mars and jupiter. Ceres, largest 940 km across, 10 4 mass of the earth. Belt probably left over material that never formed a planet. Few asteroids can be resolved too small, too dim. S-type dominates the inner region of the belt, c-type the outer regions. Ceres, palla, and vesta largest each over 500km across. Only two dozen or so larger than 200km across. 99% o asteroids over 100km known and 50% over 10km known. Most of the mass in th asteroid belt in the larger objects. Vesta appears to have undergone volcanism: odd for a small body. Vesta perhaps part of a larger body at one point. Galileo probe provided rst close up pictures: gaspra, ida, both s-type.
