Document Summary
What are their names: what is a plutoid, dense objects orbiting the sun that are much smaller than planets, icey objects orbiting in highly eccentric patterns, the terrestrial planets are mercury, venus, earth, and mars. They are made mostly of rocks and metal and are fairly small: the gas giants are jupiter, saturn, uranus, and neptune. This was what led to pluto not being a planet and more. How does it occur: is our solar system typical, the nebular hypothesis doesn"t make sense because how did huge planets like. Unit 2 snowplough - to create a "mini-disk", from which the terrestrial planets were formed. As uranus and neptune were ejected outward, one would certainly expect that all those small orbiting bodies (both rocky and icy) would have their orbits disturbed, and many would begin to. But, of course, on the way to the sun, they would have to pass close to all the terrestrial planets and many would likely impact.
