231 Vindobona is a largeMain beltasteroid. It was discovered byAustrian astronomerJohann Palisa on September 10, 1882.Vindobona is the Latin name forVienna,Austria, the city where the discovery was made.
Its dark surface indicates acarbon-rich composition.
Photometric observations at the Organ Mesa Observatory in New Mexico during 2012 showed arotation period of 14.245 ± 0.001 hours with a brightnessvariation of 0.20 ± 0.03 inmagnitude. This is in agreement with previous results.[3]
