[2] Koranna is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.
[3] It orbits the Sun in the central main belt at a distance of 2.3–3.0 AU once every 4 years and 4 months (1,584 days).
[1] The asteroid was first identified in June 1935 as 1935 MD at Simeiz Observatory on Crimea, where the body's observation arc begins the following month in July 1935.
Lightcurve analysis gave a rotation period of 4.45, 4.451 and 4.452 hours with a brightness variation of 0.70, 0.55 and 0.53, respectively magnitude (U=2+/3/2).
[5][7] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1209 and a diameter of 21.00 kilometers based on an absolute magnitude of 11.3.
