Planet Definition
The ongoing work on an IAU Resolution to scientifically define the meaning of the concept „planet“ is of particular interest to the public.
The IAU is the arbiter of planetary and satellite nomenclature since its inception in 1919. The boundary between planets and other solar system objects has never been defined and the recent discoveries of new objects in the solar system has made it necessary for the IAU to address this issue.
The decision process and a draft Resolution for the Definition of a Planet will be published in the conference newspaper during the first week of the General Assembly.
The IAU Executive Committee invites the General Assembly to a Plenary Discussion on the Definition of a Planet issue:
Tuesday, August 22, 12:45 - 13:45 in the Congress Hall.
The press is invited to attend.
