Add support for the DE440 JPL ephemeris #11544

Closed ayshih closed 3 years ago

ayshih commented 3 years ago

There is a new JPL ephemeris (DE440, Park et al. 2021), and JPL HORIZONS has been updated to use it as of today. astropy.coordinates.solar_system_ephemeris should be updated to enable access to DE440 (114 MB) and DE440s (31 MB), in addition to the already-supported DE430 and DE432s.

Is this critical for astropy 4.3? (Answer: Not a blocker for release but would be nice...)

eteq commented 3 years ago

Not critical, but is "easy" (hopefully not famous last words...), so milestoning 4.3

See #11601 - main question, should this be our new default? (let's discuss over in the PR)
