jsOrrery

jsOrrery is a visualization of our Solar System. It shows the accurate positions of the planets on any given date, as well as the distant stars. The accuracy of the simulation makes it possible to observe many interesting things such as Moon phases, Apparent retrograde motion of the planets, solar eclipses, etc. Also included is a visualization of Apollo 8's free return trajectory.
