Minor Planet & Comet Ephemeris ServiceThis webpage serves three purposes:
- To allow an observer to get ephemerides (utilizing the latest published elements) and/or elements for an arbitrary set of (up to 100 at a time) minor planets or comets.
- To allow an observer to check the current observability of an arbitrary set of (up to 100 at a time) minor planets, then to get ephemerides and/or elements for those deemed to be observable.
- To allow an observer to prepare an HTML document that can be placed
on their own website, with the aim of encouraging others to perform
follow-up astrometry of their minor planet discoveries. Of course,
this facility can also be used to generate a page for any arbitrary
set of minor planets.
- Once a page has been placed on your site, you can forget about it. You do not need to update the page as orbits are improved or as objects are identified or numbered--this is all handled transparently by this service. You need only modify the page as you discover new objects.
A PDF document (633 KB) describing the use of the MPES is available. (Updated 2011 Jan. 14)
