+meant to supplement functionality provided by @code{astropy} with functions
+and methods that are frequently used in the context of planetary astronomy
+with a clear focus on asteroids and comets.
+Features:
+@itemize
+@item observation planning tools tailored to moving objects
+@item photometry models for resolved and unresolved observations
+@item wrappers and tools for astrometry and orbit fitting
+@item spectroscopy analysis tools and models for reflected solar light and
+emission from gas
+@item cometary gas and dust coma simulation and analysis tools
+@item asteroid thermal models for flux estimation and size/albedo estimation
+@item image enhancement tools for comet comae and PSF subtraction tools
+@item lightcurve and shape analysis tools
+@item access tools for various databases for orbital and physical data, as
+well as ephemerides services
