The M-type asteroid has roughly a rotation period 96 hours of and measures approximately 30 kilometers (19 miles) in diameter.

Komsomolia was discovered on 25 September 1925, by Soviet astronomer Vladimir Albitsky at the Simeiz Observatory on the Crimean peninsula.

[3] Komsomolia is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.

[5] In December 2006, a fragmentary rotational lightcurve of Komsomolia was obtained from photometric observations by French amateur astronomer Pierre Antonini.

[6][7][8][9][10] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1703 and a diameter of 26.78 kilometers based on an absolute magnitude of 10.4.
