PyEphem provides the Python language with routines for computing the location of celestial objects like the sun, moon, and planets, as well as for any asteroids, comets, and earth satellites for which the caller can provide orbital elements. Rise, set, and transit times can be computed for any object, and basic coordinate computations are also supported.
