[15] The asteroid was named after Crimean physician and friend of the discoverer, Pyotr Isergin.
[10][11][12] Lightcurve analysis of the adopted result gave a rotation period of 7.59932 hours with a brightness amplitude between 0.25 and 0.36 magnitude (U=3-).
[5][6][7][8][9][13] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0677 and a diameter of 44.47 kilometers based on an absolute magnitude of 10.3.
