|Discovered by||Johann Palisa|
|Discovery date||February 9, 1882|
|A899 EC, A919 AB|
|Main belt (Themis)|
|Epoch 30 January 2005 (JD 2453400.5)|
Average orbital speed
This object is spectral C-type and is probably composed of primitive carbonaceous material. Based upon analysis of infrared spectra, it has a diameter of 59.8 ± 0.8 km. This object belongs to the Themis family, which was formed by the break-up of a larger parent body about a billion years ago.
