ASTR 151 Lecture Notes - Lecture 2: Giant Planet, Terrestrial Planet, Van Allen Radiation Belt
Document Summary
Task know density, sizes, distances of the planets. Ex: mercury and the earth have comparable densities, but the moon has . 1: in orbit around the sun/ 2. Has suf cient mass to maintain hydrostatic equilibrium (a nearly rounded shape)/ 3. Had cleared the neighborhood around its orbit has gradational dominance in its orbital zone. 6 ways to measure the planets: distance from sun known by kepler"s laws/ 2. Planets orbits are close to being in a there are 4 planets and 4 planets. What are the four terrestrial planets? knowing radius and mass plane. The conditions vary among the terrestrial planets. Only earth has in its atmosphere and. And spin about the same rate; is much slower, is slow and retrograde. Asteroids and meteoroids have compositions; are bigger. And ew through outer solar system. Task surface oxygen in its atmosphere and liquid water on its surface. Earth and mars spin about the same rate, mercury is much slower, and.
