ASTR 2310: Chapter 8
Overview of Solar System
– Two types of planets
– Physical properties of planets• Temperatures, densities, albedos, etc.
– Retention of atmosphere
– Solar System Formation• Protoplanetary disks, condensation, etc.
• Post formation processes (catering, volcanoes)

Characteristics of the Planet Types
Terrestrial Jovian– Mass Low (upto Earth) High (10x)
– Composition Rocky/Metal Gaseous High density Low density
– Rotation slow – day+ fast < 18hr
– Satellites Few Many
– Orbital radius < 2AU >5AU

Planet Masses – How? Planet Sizes – How? Planet Densities – How?
Planet Temperature more involved...
– I'll do it on the board, also see text and wiki for blackbodies as advertised..

Cratering and Volcanic Flooding
– Mercury is very much like the moon
– Venus has active volcanoes, surface hidden by clouds but not radar
