  Planet's Orbits 1.7.0
Planet's Orbits (for Windows 98/ME/2000/XP) is an accurate digital orrery with a wealth of functionality. The program uses the DE404 ephemeris (accurate for dates between 2000 B.C. and 6000 AD) for the calculation of planetary (except Pluto) and lunar positions. The calculation of the positions of the satellites of Jupiter, Saturn, and Uranus is done by the various analytic theories given in the Explanatory Supplement to the Astronomial Almanac.

  Gravitorium Pro 1.0.15
The prime purpose of Gravitorium is to let you play with ideas about gravity and gravitational systems. While it's not intended to be a highly accurate solar system simulator, at low speeds its accuracy is really pretty good. And, best of all, it lets you "play universe maker". Throw in a few extra planets, add a black hole, set a comet plunging towards the Earth! Or create an entirely new solar system from scratch.
