Working Group on Near-Earth Objects

A Working Group of IAU Divisions III and I

Chairman: David Morrison
Vice Chairman: Andrea Milani
Secretary: Richard P. Binzel

Organizing Committee: Edward Bowell, Andrea Carusi, Alan W. Harris, Syuzo Isobe, Brian G. Marsden, Robert McMillan, Karri Muinonen, Steven J. Ostro, Viktor Shor, Gonzalo Tancredi, Jana Ticha, Donald K. Yeomans.

The IAU Working Group on NEOs (WGNEO) is sponsored jointly by Division I and Division III. Unlike most IAU working groups, this WG is large, with a total membership of nearly 50, including consultants. The business of the WG is managed by the Officers and Organizing Committee listed above.


When someone predicts a close approach to Earth by an asteroid, a subcommittee of this Working Group advises the IAU on the reliability of the prediction. They act as voluntary peer reviewers of the manuscript if the author wishes to make use of the committee. The results of their evaluations, as well as other related public statements, are all linked from our Public Statements page.

The most recent IAU WGNEO Public Statement was issued 2004 December 30.

The general policy of the IAU with regard to research on and public information about NEOs is formulated in the Policy Statement issued by the IAU Executive Committee. The practical execution of this policy is organised by the IAU Working Group on NEOs of IAU Division III and the IAU Minor Planet Center.

Guidelines and membership of the technical review committee are on the Technical Review web page.
