Description:
40 pages on Copernicus' early Heliocentric model. Never published, only circulated around friends and colleagues.
1) Planets don't revolve around one fixed point; 2) The earth is not at the center of the universe; 3) The sun is at the center of the universe, and all celestial bodies rotate around it; 4) The distance between the earth and sun is only a tiny fraction of stars' distance from the earth and sun; 5) Stars do not move, and if they appear to, it is only because the earth itself is moving; 6) Earth moves in a sphere around the sun, causing the sun's perceived yearly movement; and 7) Earth's own movement causes other planets to appear to move in an opposite direction.
