Document Summary
Astro001 - lecture 6 - outer solar system (jupiter, saturn, uranus, neptune) and solar. Jupiter is 300 times the mass of the earth, but is far less dense, about 1. 3 grams per cubic centimeter, the density of milk. It has a radius of 11 times that of the earth. Made mostly of hydrogen and helium gas. Gaseous molecules of ammonia, methane, and water vapor also present; these lead to different colors. Clouds of different colors are at different altitudes. Jupiter rotates once every 10 hours, which stretches the clouds into long bands. Jupiter 12 earth years to orbit the sun. Interior temperatures and pressures very high hydrogen in liquid metallic form. In very center, likely to have rocky/metallic core. Magnetic fields 10 times stronger than earth due to the liquid metallic region; leads to aurora like on earth. Methane can convert to carbon soot and high pressures inside jupiter can compress it into diamonds.
