Bylaws of the Society, as revised in 1968, shall be known as the
Division for Planetary Sciences.
2. Enabling Authority
Article VII of the Society Bylaws, as revised in 1968, and as said
Article may be subsequently revised or amended, is hereby
incorporated in these Bylaws by reference.
The Division shall exist for the purpose of advancing the
investigation of the solar system and other planetary systems, with
special encouragement of interdisciplinary cooperation. Meetings
shall be organized to promote adequate discussion among
participants and shall attempt to provide a forum for discussion of
recent developments in planetary sciences. Studies of the Earth, Sun

The Committee will specify the professional organizations in which
membership will qualify a candidate for affiliate membership. A
person so qualified shall become an Affiliate Member, if formally
nominated by at least 2 Members or Affiliate Members of the
Division and approved by the Committee. Junior members are not
