HORIZONS Web-Interface
This tool provides a web-based limited interface to JPL's HORIZONS system which can be used to generate ephemerides for solar-system bodies. Full access to HORIZONS features is available via the primary telnet interface. HORIZONS system news shows recent changes and improvements. A web-interface tutorial is available to assist new users.

     Available time span for currently selected target body:
1599-Dec-09 to 2201-Feb-20 TT.

Times may be specified as calendar dates and optionally times (e.g. "YYYY{BC|AD}-MMM-DD {hh:mm}", where items in curly braces {} are optional) or Julian dates (e.g. "JD DDDDDDD.DDDD"). For years earlier than 1000, be sure to append 'AD' (or 'BC' as appropriate). All times are UT.

Times will be sorted in ascending chronological order on output.

Allowable time-spans for all bodies are available on a separate page.
