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 asteroid was named for American helioseismologist Rudolf Komm. [2]
Komm orbits the Sun in the inner main-belt at a distance of 1.4–2.9 AU once every 3 years and 3 months (1,178 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 official discovery observation. [4]
In October 2009, the first and so far only rotational lightcurve of 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 with an absolute magnitude of 15.7. [3]
This minor planet was named after Rudolf Walter Komm (born 1957), an American helioseismologist, who contributed in the study of solar activity. [2] The official naming citation was published by the Minor Planet Center on 6 August 2003 ( M.P.C. 49283). [6]
