Document Summary
Orbits in the main asteroid belt between mars and jupiter. White spot on ceres salt deposits from a cryo-volcano. Still active after a meteor strike 34 million years ago. Structure of ceres rocky inner core. Not round but quite a dwarf planet. Huger collision made a crater nearly size of vesta ( thrown out lots of rock shards ) Compared to pluto, charon is very large for a moon. Charon"s surface has more craters than pluto. Some meteorites are part of other bodies that were thrown off in collisions (eg. 4-vesta) Some have never been part of larger body they are like they were when solar system formed. Over 1 million asteroid larger than 1km diameter. Orbit the sun in the same direction as the planets. Not large enough to be roughly spherical. There are many icy bodies ( like pluto ) but much smaller. Dust tails heat from the sun melts off the ice and dust.
