It was discovered on 17 January 1924, by Russian-French astronomer Benjamin Jekhowsky at the Algiers Observatory in North Africa.

[4] The asteroid orbits the Sun in the central main-belt at a distance of 2.1–3.2 AU once every 4 years and 5 months (1,606 days).

[2] Tombecka has been characterized as a metallic M-type asteroid by the Wide-field Infrared Survey Explorer (WISE).

[5][6][7][8][9][10][11] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.1552 and a diameter of 31.93 kilometers based on an absolute magnitude of 10.12.

[12][13][14][a] In 2006, an international study modeled a lightcurve with a concurring period of 6.05017 hours and determined a spin axis of (4.0°, 62.0°) in ecliptic coordinates (λ,β) (Q=2).
