Observable Comets
This page lists links to orbital elements and ephemerides of (potentially) observable comets. Also available are:- a list of comets discovered in the past year
- dates of last observation for currently-observable comet
- the text of the 1994 IAU resolution implementing the current comet designation system
- orbital elements in forms suitable for loading into popular planetarium-type programs
- recent magnitude estimates of comets as reported to the International Comet Quarterly (links to the magnitudes are also given from the pages for individual comets shown below).
