BoPlanets

BoPlanets is a virtual planetarium, which shows the positions of the planets in the solar system relative to an observing planet, which can be selected out of the planets and the sun. The planets can be shown in the ecliptic view in Cartesian coordinates and in the equatorial view with right ascension and declination.
You can let the planets move by single steps or let them run continuously. The speed may be varied by a speed slider.
The version BoPlanets-Plus additionally contains the horizon view, which shows the daily movement of the planets relative to the horizon of an observer..With BoPLanets-Plus a list of rise, transits and set times of a planet as seen by an observer may be generated.
