US copyright law has a creativity requirement. Just how much
"creativity" is required is ambiguous.
European copyright law typically has a "seat of the brow" component,
which means under European Copyright law, it would copyright. (That EU
directive doesn't throw out copyright on "sweat of the brow" grounds.)

The creativity here is:
* Which bodies are included;
* How frequently are the co-ordinates listed - hourly, daily, weekly,
monthly, annually, etc.;
* What unit of measurement is used for those co-ordinates;
* What is the starting point of the listings;
* What is the ending point of the listing;

Astrolabe, Inc. v Arthur David Olson and Paul Eggert
Massachusetts District Court 1:2011cv11725
implies that a case to the contrary can be made.

not a legally recognised thing.
What is needed is a specific license for the JPL Planetary Ephemeris,
that is congruent with the Debian Social Contract.
