32145 Katberman ( provisional designation 2000 LE30) is a stony asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter. The asteroid was discovered on 7 June 2000, by the LINEAR team at Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico, United States. It was named for Katharine Berman, a 2016 Intel STS awardee. [2]
Katberman orbits the Sun in the inner main-belt at a distance of 2.0–2.8 AU once every 3 years and 9 months (1,370 days). Its orbit has an eccentricity of 0.18 and an inclination of 9 ° with respect to the ecliptic. [1]
The asteroid's observation arc begins 4 years prior to its official discovery observation, with a precovery taken by the Steward Observatory's Spacewatch survey at Kitt Peak in June 1996. [2]
According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Katberman measures 4.4 kilometers in diameter and its surface has an albedo of 0.16, [4] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for a stony asteroid of 0.20 and calculates a diameter of 2.9 kilometers with an absolute magnitude of 15.04. [3]
In October 2012, and January 2014, three rotational lightcurves of Katberman were obtained from photometric observations at the Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of 9.14, 9.17 and 9.13 hours, respectively, with a corresponding brightness variation of 0.85, 0.80 and 0.70 in magnitude ( U=2/2/2). [6] [7]
This minor planet was named after Katharine Barr Berman (born 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. [2] The official naming citation was published by the Minor Planet Center on 21 May 2016 ( M.P.C. 100315). [9]
