Unconfirmed sightings of the asteroid it had previously been a number: for example, on 12 January 1926, the provisional designation 1926 AJ at the Hamburg Observatory in Bergedorf, on 26 November 1940 ( 1940 WB) at the French Observatoire de Nice, and on 28 January 1952 (1952 BH1 ) at the McDonald Observatory in Texas.

The mean diameter of the asteroid was determined with 29.49 ( ± 1.6 ) km. With an albedo of 0.09, the rounded surface is quite dark. The light curve was measured at the Observatoire de Genève ( Geneva Observatory ) - in August 2001 by Laurent Olivier Bernasconi and Thizy and then again in July 2006 by René Roy - and has a period of about 9 hours.

( 2140 ) was named after Kemerovo Kemerovo on 8 February 1982 a Russian town in western Siberia.
