python3-ephem 3.7.7.0-2build2 (armhf binary) in ubuntu focal

 PyEphem provides an ephem Python package for performing high-precision
 astronomy computations. The underlying numeric routines are coded in C and
 are the same ones that drive the popular XEphem astronomy application, whose
 author, Elwood Charles Downey, generously gave permission for their use in
 PyEphem.

 The name ephem is short for the word ephemeris, which is the
 traditional term for a table giving the position of a planet, asteroid, or
 comet for a series of dates.
