The first version of BoPlanets was released.
BoPlanets is a virtual planetarium written in Java. It shows the movements of the planets relative to a selectable observing planet. The planets may be shown in the ecliptical, equatorial or horizontal view. The planets may be moved step by step or in continuous mode.
You may see the epicycles of the planets with the earth as center of the universe. Or you may see the dayly motion of the sun as seen by the mercury.
