(3267) Glo Mars-crossing Asteroid
Discovered on 3 January 1981 by E. Bowell at Anderson Mesa.
Named in honor of Eleanor F. (“Glo”) Helin, planetary scientist at the Jet Propulsion Laboratory, in appreciation of her extraordinary contributions to the discovery of near-Earth minor planets. Her finding of 1976 AA (= 2062 Aten) heralded the recognition of a new class of planet crossers, and her initiation of the Palomar planet-crossing asteroid survey has resulted in increased worldwide interest in the observation of minor planets. Helin's education and experience as a geologist and in the analysis of meteorites has provided a unique background for her interest in asteroids and comets. Citation prepared by R.
