Document Summary

Unit 1: the planets of the solar system and their motions. Asterism: prominent pattern or group of stars, typically having a popular name but smaller than a constellation. Celestial sphere: a sky map with coordinates, comparable to latitude/longitude on earth; stars are fixed on the sphere like cities on a map divided into 88 constellations. Constellation: entire regions of the sky and everything in them asterisms and constellations are often named the same which causes confusion. Using the earths equator and n/s poles, we establish the celestial equator and celestial poles to divide the sphere into declination (latitude; measured 0-90 of the celestial equator; (cid:1039)) and right ascension (ra; longitude; measured 0-24hr; (cid:1040)) Ecliptic: the apparent annual path of the sun on the celestial sphere; the earth ecliptic as seen from the sun is the same. The celestial equator and the sun are tilted in relation to each other 23. 5 and meet in 2 spots.
