DE
What does the DE in DE406 mean? I've looked for a definition, but found nothing so far. It probably derives from 'Digital Ephemeris', or 'discrete ephemeris', but I'd welcome any other suggestions. Pavium (talk) 02:13, 1 January 2009 (UTC)


 * DE stands for Development Ephemeris as in the article "JPL Development Ephemeris number 96". — Joe Kress (talk) 08:41, 2 February 2009 (UTC)

Ephemerides of moons
Hi, as far as I understand these tables can provide states for the solar system planets, of it's barycenter and of earth-lunar system. What about the other moons, like Mars' Phobos and Deimos? When I want to include those how do I get it? Are there other tables for it? thanks in advance, --Andreas -horn- Hornig (talk) 11:56, 15 May 2010 (UTC)


 * DE405 includes ephemerides for Mercury, Venus, Earth-Moon barycenter, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, Sun, Moon, plus nutations and librations. No satellites other than the Moon are included. However, JPL Horizons provides ephemerides for 513611 asteroids, 3050 comets, 170 planetary satellites, 8 planets, Sun, L1, L2, spacecraft and barycenters. — Joe Kress (talk) 08:16, 16 May 2010 (UTC)

Rename the article?
We might consider renaming this. As far as I know, there was never any ephemeris from JPL called "DE400". Tfr000 (talk) 14:47, 4 January 2012 (UTC)

It might be a also good idea to merge this article with Jet_Propulsion_Laboratory_Development_Ephemeris, so all of the DE-series will be in the same place. Tfr000 (talk) 19:01, 4 January 2012 (UTC)
