[19] The asteroid was named after female paratrooper Tamara Ivanova, who died at an early age.
[10][11][12][13][14][15][16][17][18] Analysis of the best-rated lightcurve by French amateur astronomer Pierre Antonini gave a period of 6.1961 hours with a brightness amplitude of 0.42 magnitude (U=3).
[3][16] According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Tamariwa measures between 24.71 and 30.681 kilometers in diameter and its surface has an albedo between 0.0916 and 0.15.
[5][6][7][8][9] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.1165 and a diameter of 27.19 kilometers based on an absolute magnitude of 10.78.
