Xplanet was inspired by Xearth. It renders images on the desktop background.
All of the major planets and most satellites can be drawn, similar to a Solar System Simulator. A number of different map projections are also supported, including azimuthal, Mercator, Mollweide, orthographic and rectangular.
A bunch of useful scripts are separately available: to update your maps with the latest cloud images, satellite orbits, weather information, and recent volcanoes and earthquakes, and create images with different projections and viewpoints; to create marker files for earthquakes, volcanoes, hurricanes, and satellites, as well as the markerfiles themselves and a cloud map mirror.
Check the homepage to find about these scripts and the available texture maps.
This is the Port for FreeBSD. Source for Linux, Darwin and Mac OSX compilation and a Windows version are also available.
