From Jan Horn:
Solar System Information Portable is an application that shows some information about the planets and their moons in our solar system. With this application you can view information about the Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and even Pluto, the icy sphere that's no longer considered a planet. Each planet and satellite comes with a 3D representation that you can move around with the help of your mouse. The planetary info includes the name, the distance from the Sun in Astronomical Units (1 Astronomical Unit is equal to the distance from the Sun to the Earth), diameter in kilometers, volume, mass and gravity in comparison with our planet, temperature, and length of day.
