'''32145 Katberman''' (provisional designation '''{{mp|2000 LE|30}}''') 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.<ref name="MPC-Katberman" />
== Orbit and classification == 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.<ref name="jpldata" />
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.<ref name="MPC-Katberman" />
== Physical characteristics ==
=== Diameter and albedo === 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,<ref name="WISE" /> 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.<ref name="lcdb" />
=== Rotation period === 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 {{val|9.14}}, {{val|9.17}} and {{val|9.13}} hours, respectively, with a corresponding brightness variation of 0.85, 0.80 and 0.70 in magnitude ({{small|U=2/2/2}}).<ref name="Waszczak-2015" /><ref name="Chang-2015" />
== Naming == 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.<ref name="MPC-Katberman" /> The official naming citation was published by the Minor Planet Center on 21 May 2016 ({{small|M.P.C. 100315}}).<ref name="MPC-Circulars-Archive" />
