Working Group of IAU Division F-Planetary Systems and Bioastronomy

The Working Group for Small Bodies Nomenclature (originally the Committee for Small Bodies Nomenclature - CSBN) has a responsibility, under the authority of the IAU, for the names of the small bodies (except satellites of the major planets) in the solar system - minor planets (asteroids), comets and satellites of minor planets. WG-SBN together with WG-PSN is responsible for naming of dwarf planets. The actual naming is administered, under the guidance of the WG, by the Minor Planet Center (MPC). The committee has also the responsibility for the designations of these bodies.


The members of the WG for the 2018-2021 triennium are:

Chair: Jana Tichá (Czech Republic)
Vice-Chair: Keith Noll (USA)
Secretary and MPC Rep: Gareth V. Williams (USA)

Naming Small Bodies

Basic info about naming of minor planets.

Basic info about naming of comets.

There is the alphabetical list of all named minor planets.

More detailed guidelines for minor planet naming are available here.

However, neither the CSBN nor the IAU or MPC sells names of comets or asteroids to the public. This derives from the general policy of the IAU on selling names for celestial bodies which you can read at the IAU web site.
