Document Summary
Describe the shape and major motions ( orbit, rotation) of objects in the solar. Recognize major patterns of motion in the solar system, and relate these to its formation mechanism. Identify key properties of each planet, emphasizing commonalities and exceptions. Become familiar with currently-active space missions to study the solar system. Comparative planetology: comparing worlds to one another, seeking to understand their similarities and differences. R: 669,00km = 108 x of earth. Moons: 0: heavily cratered, days and nights lasting 3 earth months each, past geological activities: ancient lava flows, steep cliffs, magnetic field but we don"t know why. Small, rocky, thin or no atmosphere, few moons, made of heavy elements. Surface temperature: 290 k: rotates on axis in the opposite direction of earth, days are long and the sun rises in the west, past volcanic and geological activity, extreme greenhouse effect traps in all the heat.
