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

Seeliger, who proposed the name to the discoverer, was later honored with asteroid 892 Seeligeria, discovered by Max Wolf in 1918.

[6][12] In the SDSS-based taxonomy, it is an L-type asteroid[13] In December 2000, a rotational lightcurve of Sophia was obtained from photometric observations by Bill Holliday in New Braunfels, Texas.

[10] Between 2005 and 2013, additional observations by French amateur astronomers Laurent Bernasconi, Etienne Morelle and René Roy gave a tentative period of 20.28 hours with an amplitude between 0.25 and 0.61 (U=2/2/2).

[7][8][9] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.2377 and a diameter of 28.54 kilometers based on an absolute magnitude of 9.9.
