[2] Benda is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.
[2] Benda is an X-type asteroid in both the Tholen- and SMASS-like taxonomic variants of the Small Solar System Objects Spectroscopic Survey (S3OS2).
[13] In October 2013, a rotational lightcurve of Benda was obtained from photometric observations over two nights by Robert Stephens at the Center for Solar System Studies (U81) in California.
[15] In September 2018, a collaboration of the Italian Amateur Astronomers Union reported a period of 7.105±0.001 hours with a brightness variation of 0.25±0.03 magnitude (U=3–).
[7][8][9] The Collaborative Asteroid Lightcurve Link derives a low albedo of 0.0387 and a diameter of 70.71 kilometers based on an absolute magnitude of 9.9.
