xplanet is similar to xearth, where an image of the earth is rendered into the X root window. Various projection systems are available for display. All of the major planets and most satellites can be drawn.
This package consists of two images, earth.jpg and night.jpg that can be used with xplanet. For links to other planet maps, see /usr/share/doc/xplanet/README.Debian.
