Visual Planets - Version 2.0a A multimedia excursion around our Solar System. The program, already a classic, extends and deepens our acquaintance with the Sun and its nine Planets, using the power of hypertext to connect images to information about each body's moons, atmosphere, structure, rings, statistics, mythology, and the spacecraft that have done more than anything else to probe their secrets. Unfamiliar astronomical terms are equipped with yet further hyperlinks to more definitions.
