ASTRON 10 Lecture Notes - Lecture 9: Volatiles, Oort Cloud, Comet Nucleus
Document Summary
Manner of solar system learning in this class is different from the one for the 200 years, relying on the connections between the solar system objects. Looking at parts of an object and making assumptions that end up being wrong. We are a tiny5 part of the universe. Images that show the relative size of solar system objects grossly distort the lengths between them. No way to show both pieces of data accurately. A logarithmic temperature vs. logarithmic mass can be used to see relationships between different objects in the solar system. Nebulae without ice comes mainly from star death*origin of supernovae. For one or several reasons, it condenses enough to hold itself together gravitationally. An average direction of rotation is reached after collisions average out random motions. Conservation of angular momentum is the reason. They collide with other objects if they aren"t in the equatorial region of the cloud. Dust grains clump to planetesimals, which further clump to protoplanets.
