32145 Katberman, provisional designation 2000 LE30, is a stony asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter. It was discovered by the U.S. LINEAR team at Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico, on 7 June 2000.
The S-type asteroid orbits the Sun at a distance of 2.0–2.8 AU once every 3 years and 9 months (1,371 days). Its orbit has an eccentricity of 0.18 and an inclination of 9° with respect to the ecliptic. The first precovery was taken at Steward Observatory (Kitt Peak-Spacewatch) in 1996, extending the asteroid's observation arc by 4 years prior to its discovery.
According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, the asteroid measures 4.4 kilometers in diameter and its surface has an albedo of 0.16, while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 2.9 kilometers, based on an absolute magnitude of 15.04.
In October 2012 and January 2014, three rotational light-curves were obtained from photometric observations made at the U.S Palomar Transient Factory in California. The light-curves gave a rotation period of 7000914000000000000♠9.14, 7000917000000000000♠9.17 and 7000913000000000000♠9.13 hours, respectively, with a corresponding brightness variation of 0.85, 0.80 and 0.70 in magnitude (U=2/2/2).
The minor planet was named after Katharine Barr Berman (b. 1998) awardee in the Intel Science Talent Search of 2016. She was a finalist for her cellular and molecular biology project. At the time, she attended the U.S. Hastings High School in New York. Naming citation was published on 21 May 2016 (M.P.C. 100315).
