Distant Suns - Grand Tour 3D Screensaver

From First Light Software: Distant Suns - Grand Tour 3D Screensaver is a high-speed, full-motion, solar-system simulator using OpenGL technology and accelerated graphics. The positions and rotations of each of the planets and its moons are accurate to the current date and time (making the program a clock of sorts). As the day progresses, you can observe the great red spot of Jupiter as it wheels across the face of the giant planet. Watch the moons of Saturn in their daily dance around the majestic ringed world, and watch Earth rotate under your feet. The constantly changing scenes assure an infinite variety of interplanetary vistas. Grand Tour 3D now comes with Phobos and Deimos, the moons of Mars, and features the Mars Rover landing sites. Version 1.22 build 1 may include unspecified updates, enhancements, or bug fixes.
