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

[4] It orbits the Sun in the central main belt at a distance of 2.1–3.3 AU once every 4 years and 5 months (1,621 days).

[10] In July 2000, a rotational lightcurve of Dolores was obtained from photometric observations by American astronomer Robert Stephens.

Lightcurve analysis gave a well-defined rotation period of 17.19 hours with a brightness amplitude of 0.45 magnitude (U=3), indicative of a somewhat elongated shape.

[5][6][7][8] The Collaborative Asteroid Lightcurve Link adopts the result obtained by IRAS, that is, an albedo of 0.0879 and a diameter of 27.64 kilometers based on an absolute magnitude of 11.05.
