Sean E Urban's book: astronomical almanac 

JPL Horizons provides interpolated results from spice kernels. The spice kernels contain blocks of interpolation coefficients using (usually if not always) Chebychev polynomials that allow spice users, other third party programs, and the Horizons website to calculate positions in-between the points where the coefficients are provided in the kernels.

astroplan:

astroplan is an open source Python package to help astronomers plan observations.

The goal of astroplan is to make a flexible toolbox for observation planning and scheduling. When complete, the goal is to be easy for Python beginners and new observers to to pick up, but powerful enough for observatories preparing nightly and long-term schedules.
