BoPlanets-Plus

BoPlanets-Plus 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 various views. In the ecliptic view the Cartesian coordinates, in the equatorial view right ascension and declination, in the horizon view azimuth and altitude of the planets relative to an observing planet are displayed. In the horizon view the position of the observer on the observing planet can be the current location of the phone (the location of the phone on the planet is the same as on earth) or can be determined by an address (analogical to the earth as observing planet).
You can let the planets move by single steps or let them run continuously. The speed may be varied by a speed slider.
A list of rise, transit and set times of a planet, as seen by an observer on the observing planet, may be generated.
