How Names Are Approved

When images are first obtained of the surface of a planet or satellite, a theme for naming features is chosen and a few important features are named, usually by members of the appropriate IAU task group. Later, as higher resolution images and maps become available, additional features are named at the request of investigators mapping or describing specific surfaces, features, or geologic formations. Anyone may suggest that a specific name be considered by a task group, but there is no guarantee that the name will be approved. If the members of the task group agree that the name is appropriate, it can be retained for use when there is a request from a member of the scientific community that a specific feature be named. Names successfully reviewed by a task group are submitted to the Working Group for Planetary System Nomenclature (WGPSN). Upon successful review by the members of the WGPSN, names are considered approved and can be used on maps and in publications. Approved names are immediately entered into the Gazetteer of Planetary Nomenclature. Any objections to these names based on significant, substantive problems must be forwarded in writing or email to the IAU Division III President within three months from the time the name was placed on the web site. Approved names are also listed in the transactions of the IAU.

Suggestions should be sent to the president of the WGPSN, to the chairman of the appropriate task group, or to the USGS Astrogeology Research Program, attention Jennifer Blue, 2255 N. Gemini Drive, Flagstaff, Arizona 86001, or by e-mail; jblue@usgs.gov.
