Aciqra

Aciqra is a portable planetarium. While it's not quite as good as Celestia or Stellarium, it has some interesting features that make it stand out nonetheless.

First and foremost, it is a virtual display of the solar system in real time. Aciqra shows the current position of the elements in the sky: planets, stars, nebulae, galaxies, constellations, and so on.

You can set it to show you the part of the sky that you can see from your location or anywhere on earth.

Some other features include information on spatial ephemeris (elongation, phase, angular diameter), the orbit of the planets in the solar system, and solar events (such as solar and lunar eclipses, or Mercury and Venus transits).
