39741 Komm, provisional designation 1997 AT6, is a stony asteroid and eccentric Mars-crosser from the innermost regions of the asteroid belt, about 2 kilometers in diameter. It was discovered by American astronomer Roy Tucker at the U.S. Goodricke-Pigott Observatory in Tucson, Arizona, on 9 January 1997.[5]
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 shows a high eccentricity of 0.35 and is tilted by 6 degrees to the plane of the ecliptic. It has a provisional rotation period of almost 6 hours[4] and an assumed albedo of 0.20.[3]
The minor planet was named after American helioseismologist, Rudolf Walter Komm (b.1957), who contributed in the study of solar activity.[2]
