python3-jplephem - 2.22+ds-1 main

This package can load and use a Jet Propulsion Laboratory (JPL)
ephemeris for predicting the position and velocity of a planet or other
Solar System body. It currently supports binary SPK files (extension
".bsp") like those distributed by the Jet Propulsion Laboratory
that are:
.
* Type 2 - positions stored as Chebyshev polynomials, with velocity
derived by computing their derivative.
* Type 3 - positions and velocities both stored explicitly as
Chebyshev polynomials.
* Type 9 - a series of discrete positions and velocities, with
separate timestamps that do not need to be equally spaced. Currently
there is only support for linear interpolation: for Type 9 ephemerides
of polynomial degree 1, not of any higher degrees.
.
Even if an ephemeris isn't one of the above types, it is still possible
to use jplephem to read its text comment and list the segments inside.
