Skyfield is a pure-Python astronomy package that is compatible with
both Python 3 and makes it easy to generate high precision
research-grade positions for planets and Earth satellites.
.
Skyfield computes positions for the stars, planets, and satellites in
orbit around the Earth. Its results should agree with the positions
generated by the United States Naval Observatory and their
Astronomical Almanac to within 0.0005 arcseconds (which equals half a
“mas” or milliarcsecond).
