Swiss Ephemeris 2.0

The Swiss Ephemeris is a high-precision ephemeris based on the DE406 ephemeris from NASA's JPL. It is built on the most recent planetary and lunar ephemeris, DE405/406, developed by the Jet Propulsion Laboratory of NASA. The original integration, DE405, covers the years 3000 BC to 3000 AD and requires 550 megabytes of disk space.
