Description

The Minor Planet Mailing List {MPML} is the active list for the minor planet community. You will find MPML is populated with many of the world's best amateur astronomers as well as many professional astronomers involved in all facets of asteroid and comet research.

MPML is open to all with an interest in asteroids and comets. However, since many active MPML members are seriously involved in this field of research, the posts to this list can often be rather technical.

The MPML archives are available to all as a service to the astronomical community. To post on MPML you must be a member.

Clear Skies,
Richard Kowalski
MPML Administrator
