290 Bruna is a main belt asteroid that was discovered on March 20, 1890 by Johann Palisa, an Austrian astronomer at the Vienna Observatory.

Photometric observations of this asteroid at the Organ Mesa Observatory in Las Cruces, New Mexico during 2008 gave a light curve with a period of 13.807 ± 0.001 hours and a brightness variation of 0.54 ± 0.04 in magnitude. Changes in the brightness of the minimum with phase angle is attributed to changes in the shadows across surface features.
