ASTR 101 Lecture Notes - Lecture 4: Celestial Pole, Coriolis Force
Document Summary
Coriolis force pushes us to the west, while gravity pushes us down. Earth is moving west to east (counterclockwise when viewed from the top down), while the celestial sphere rotates east to west. Other planets also move counterclockwise when viewed from the top down or clockwise when viewed from bottom up. Planet is tilted 23. 5 degrees due to collision with object as large as mars. Stars rise in the east and set in the west. North celestial pole and south celestial pole is point where stars don"t look like they"re moving, but this is where they rotate. Two types : stars that never set and stars that never rise. If in north pole and south pole, 100% of the stars are circumpolar.
