39741 Komm, provisional designation 1997 AT6, is a stony asteroid and eccentric Mars-crosser from the innermost regions of the asteroid belt, approximately 2 kilometers in diameter. It was discovered on 9 January 1997, by American astronomer Roy Tucker at Goodricke-Pigott Observatory in Tucson, Arizona, United States.[4]
The S-type asteroid orbits the Sun at a distance of 1.4–2.9 AU once every 3 years and 3 months (1,177 days). Its orbit has an eccentricity of 0.35 and an inclination of 6° with respect to the ecliptic.[1] As no precoveries were taken, the asteroid's observation arc begins with its discovery observation.[4]
In October 2009, the first and so far only rotational light-curve for Komm was obtained by French amateur astronomer René Roy. It gave a well-defined rotation period of 5.95±0.01 hours with a high brightness variation of 0.83 magnitude, indicative of a non-spheroidal shape (U=3).[5]
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 2.15 kilometers, based on an absolute magnitude of 15.7.[3]
The minor planet was named after Rudolf Komm (b. 1957), an American helioseismologist, who contributed in the study of solar activity.[2] Naming citation was published on 6 August 2003 (M.P.C. 49283).[6]
