Ephemeris system
JPL Development Ephemeris
The series of numerically-integrated ephemerides, produced by NASA's Jet Propulsion Laboratory, that give the positions and velocities of the planets, the Moon, and the Sun to high precision over long spans. The DE ephemerides are the standard reference for precise Solar System calculations.
