2140 Kemerovo, provisional designation 1970 PE, is a 30-kilometer sized X-type asteroid from the outer regions of the asteroid belt. It was discovered by Russian female astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj on 3 August 1970.[8] The asteroid orbits the Sun at a distance of 2.8–3.2 AU once every 5 years and 2 months (1,885 days). It has a rotation period of 9.2 hours.[7]
Measurements of its albedo vary from 0.054 (NEOWISE misison) to 0.089 (IRAS) while detections by Akari's mid-infrared sensors as well as derived calculations from the LCDB project indicate a geometric albedo of 0.076 and 0.062, respectively.[3][5]
It is named after Kemerovo Oblast, the regional center of the Russian Kemerovo district, and a significant industrial center in Siberia.[2]
