It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 3 October 1911,[3] and subsequently a lost minor planet for 89 years.
The asteroid was named in memory of Albert Salomon Anselm von Rothschild, an Austrian philanthropist and banker.
[1] The asteroid's first observation is a precovery taken in September 1911 at Heidelberg Observatory, two weeks prior to its discovery at Vienna.
[13] Upon further investigation, however, it was noticed that its orbital plane matched up nicely with the last remaining "lost" asteroid and it was properly identified.
During this pass its rotational period was calculated at 5.802 hours and a measured absolute magnitude of 15.43 together with an assumed albedo of 0.12 gave a diameter of 2.8 km.
[6] Another group led by R. P. Binzel measured an absolute magnitude of 15.8; they, however, used an assumed albedo of 0.15 leading to a calculated diameter of 2.4 km.
