Document Summary

Geocentric perspective: consists of sun, planets, asteroids and etc. Ptolemy: planets orbit in small circles (epicycles)therefore more. Copernicus proposed that mars was closest to earth because it had predictable retrograde motion. the largest retrograde motion, and saturn having a smaller retrograde made it furthest. Also proposed that sunrise and sunset occurs because of. Earth"s spin on its" axis: law of orbital harmony: Every planet forms an ellipse which is an orbit with the: law of ellipses: sun as the focus the square of the orbital in years is proportional to the cube of the planet"s avg distance from the sun. Planet moves faster near the sun, so the same area is swept out in given time as at larger distances, where the planet moves more slowly. are equal. The orbital velocity changes: law of equal areas. : area from the planet to the sun represents time, which. Largest temperature range from -170- 425 oc.
