[2][11] Leuschneria is a carbonaceous C-type asteroid that orbits the Sun at a distance of 2.7–3.5 AU once every 5 years and 5 months (1,976 days).

[2] In May and June 2015, two rotational lightcurves of Leuschneria were obtained from photometric observations by Maurice Clark at Preston Gott Observatory of Texas Tech University, United States, and by Giovanni Casalnuovo at Eurac Observatory (C62) in Bolzano, Italy.

Lightcurve analysis gave a rotation period of 12.0893 and 9.646 hours with a brightness amplitude of 0.75 and 0.19 magnitude, respectively (U=2/2-).

[8][9] According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Leuschneria measures between 29.637 and 33.47 kilometers in diameter and its surface has a respective albedo between 0.066 and 0.0779.

[4][5][6][7] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0773 and a diameter of 30.16 kilometers with an absolute magnitude of 11.0.
