About Teskooano

Teskooano (pronounced tes-koo-ah-no) is a 3D N-body simulator that runs in your browser. Every body in a system pulls on every other, so planets, moons, comets and satellites move as gravity says they should. You can watch our own Solar System, placed from real orbital elements, or generate a new star system from any seed.

The name comes from G. I. Gurdjieff’s Beelzebub’s Tales to His Grandson, where a Teskooano is the great telescope in Beelzebub’s observatory on Mars, used to observe the distant concentrations of the Universe.
