Minor Planet Electronic Circulars
The Minor Planet Electronic Circulars (MPECs)
carry news on unusual
minor planets and some routine material on comets. New discoveries
of unusual minor planets (both near-Earth and
trans-Neptunian objects) are now announced via these circulars.
Improved orbits appear frequently. Monthly lists of observable
unusual objects, observable distant objects, observable comets and the
critical list of numbered minor planets also appear on these circulars.
