Document Summary
1. 1 definitions and locations: pluto was demoted to dwarf planet status more objects almost identical to. Pluto were being discovered: plutoid was introduced to describe pluto-like trans-neptunian dwarf planets, trans-neptunian objects = any sized objects in the solar system that orbit. Sun at a greater distance than neptune; includes everything in kuiper belt and oort cloud. Sun, and freezes when it draws away: tidal lock between pluto and charon suggests an age of tidal heating that may have drive geological activity; seasonal vaporization and refreezing of ices may have erased or covered the surface. 4. 2 other known tnos: likely much less space between icy objects in the kuiper belt. 2. 1. 3 the tail: dust tail = small dust particles that sputter off the nucleus; reflects sunlight therefore is visible. Ion tail = made of glowing gas; pushed away from sun by solar wind.
