Xplanet was inspired by Xearth, which renders an image of the earth into the X root window. All of the major planets and most satellites can be drawn, similar to the Solar System Simulator. A number of different map projections are also supported, including azimuthal, Lambert, Mercator, Mollweide, orthographic, and rectangular. Xplanet is free software, distributed according to the terms of the GNU General Public License. Original version written by Frank Solensky , updates by Hari Nair Xplanet in its default mode will now draw multiple bodies. For example, when drawing Jupiter, any of the Galilean satellites in the field of view will also be drawn. For this reason, options that are specific to a body, such as the image map or marker files, are now specified in a configuration file. Options that affect the way the image is drawn, such as geometry or label, are still specified on the command line. The subdirectories under share/xplanet (e.g. arcs, markers, satellites) each contain README and example files for more information. HOME PAGE: http://xplanet.sourceforge.net/
