Skyfield: Home • Table of Contents • Changelog • API Reference
Skyfield includes some contributed code that can compute predicted positions for minor planets and comets given simple Kepler orbital elements. The computations are not yet very fast, and can’t yet compute multiple body positions efficiently using NumPy array operations—if you ask for ten comet positions, then Skyfield has to run an internal loop computing each of the ten positions separately.
The library is not yet fully documented; see Kepler Orbits for an introduction to the features it already supports.
Here, we have only yet documented the routines for loading data, as they are the most stable.
