The Solar System Visualizer
, created as part of an independent study at the University of Maryland, shows the motion of a primary object's satellites such as Mars, Uranus or Neptune. It is also possible to watch a visualization of extrasolar systems. The application calculates each satellite's motion using orbital elements. Michael VanDaniker and Andrew Lund, the site's creators, explain that future plans for this project include taking the orbits into 3D, expanding on the extrasolar system data, and the inclusion of Kuiper Belt objects.
