[13] In the SMASS classification, Zhongolovich is characterized as a Ch-subtype, a carbonaceous C-type asteroid which shows evidence of hydrated minerals.
[1] In August 2011, a rotational lightcurve of Zhongolovich was obtained from photometric observations by French amateur astronomer Pierre Antonini.
Lightcurve analysis gave a well-defined rotation period of 7.171 hours with a brightness variation of 0.21 magnitude (U=3).
[6][7][8][9][10] The Collaborative Asteroid Lightcurve Link agrees with the results obtained by IRAS, that is, an albedo of 0.0456 and a diameter of 28.47 kilometers with an absolute magnitude of 11.7.
[3] This minor planet is named in honor of Russian astronomer and geodesist Ivan Danilovich Zhongolovich, who was the head of the Special Ephemeris Department at the Institute of Theoretical Astronomy (ITA) in St Petersburg.
