High Quality Content by WIKIPEDIA articles! Tom Gehrels (born February 21, 1925, Haarlemmermeer, the Netherlands) is an American astronomer, Professor Planetary Sciences, and Astronomer at the University of Arizona, Tucson. Gehrels pioneered the first photometric system of asteroids in the 50s, and wavelength dependence of polarization of stars and planets in the 60s, each resulting in an extended sequence of papers in the Astronomical Journal. He has discovered, jointly with the husband and wife team of Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld, over 4000 asteroids, including Apollo asteroids, Amor asteroids, as well as dozens of Trojan asteroids. That was done in a sky survey using the 48-inch Schmidt telescope at Palomar Observatory and shipping the plates to the two Dutch astronomers at Leiden Observatory, who analyzed them for new asteroids. The trio are jointly credited with several thousand discoveries. Gehrels also has discovered a number of comets.
