It was discovered by Austrian astronomer Johann Palisa on September 10, 1882. Vindobona is the Latin name for Vienna, Austria, the city where the discovery was made. Its dark surface indicates a carbon-rich composition. Photometric observations at the Organ Mesa Observatory in New Mexico during 2012 showed a rotation period of 14.245 ± 0.001 hours with a brightness variation of 0.20 ± 0.03 in magnitude. This is in agreement with previous results.
