AST101H5 Chapter Notes - Chapter 8: Kuiper Belt, Oort Cloud, Compressed Hydrogen
Document Summary
Ball of incandescent gas whose light and heat are generated by nuclear reactions in its core. 700 times the mass of all other items in the solar system put together. Smaller than the sun, orbit the sun in nearly circular orbits. Small rocky bodies with relatively thin or no atmosphere. Gaseous and liquid with deep hydrogen rich atmospheres. Hella small, mad icey, and a super awks orbit. To be a dwarf, the body has to: Be massive enough that its gravity compresses it into an approximately spherical shape. Have been unable to sweep its orbital region clear of other objects that add up to a mass comparable to its own mass. Gravity isn"t strong enough to pull themselves into shape and classify as dwarf planets. A large belt between mars and jupiter. Similar to the asteroid but objects are made of mostly ice.
