9423 Abt

9423 Abt, provisional designation 1996 AT₇, is a stony asteroid from the middle region of the asteroid belt, about 13 kilometers in diameter. It was discovered by the U.S. Spacewatch project of the University of Arizona at Kitt Peak National Observatory, on 12 January 1996.

The S-type asteroid orbits the Sun at a distance of 2.4–3.0 AU once every 4 years and 5 months (1,614 days). Its orbit shows an eccentricity of 0.10 and is tilted by 9 degrees to the plane of the ecliptic. A photometric light-curve observation at Hunters Hill Observatory, Australia, in 2006 gave it a rotation period of 7000328100000000000♠3.281±0.005 hours with a brightness amplitude of 0.30 in magnitude. A second light-curve analysis took place at the Palomar Transient Factory survey in 2012, rendered a concurring period of 7000327660000000000♠3.2766±0.0003 hours with an amplitude of 0.33 in magnitude.

According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of the U.S Wide-field Infrared Survey Explorer, the asteroid's surface has an albedo of 0.14 and 0.13, respectively, while the Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.10, which is untypically low for stony bodies. Both, the space-based surveys and CALL agree closely on a diameter estimate in the range of 12.69 to 13.29 kilometers.
