ASTR 150 Lecture Notes - Lecture 5: Olympus Mons, Mainframe Computer, Impact Crater
Document Summary
Astr150 lecture 4: the origin of the moon. The moon stabilizes the earth"s obliquity and keeps it locked at about 23. 5 degrees. The larger the surface area to volume ratio, the quicker a planet loses its heat. It is the closest planet to the sun and is in the big chill phase. This density is fairly big, which means it has a very big iron core. Has jumbled terrain on one side opposite the large impact crater. Martian craters - liquid locked into the crust. More geologically complex in comparison to mars. There was at one point water on mars. Northern hemisphere is composed of mare while the southern hemisphere is mainly highlands. Tharsis regions around the volcanoes are very young. Olympus mons: largest volcano in the solar system and is almost the size of washington while being 14 miles high.
