460 Scania

It was discovered by German astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory on 22 October 1900.

[1] The uncommon K-type asteroid has an exceptionally long rotation period of 164.1 hours and measures approximately 21 kilometers (13 miles) in diameter.

Lightcurve analysis gave a well defined rotation period of 164.1±0.1 hours with a brightness variation of 0.37±0.03 magnitude (U=3).

[10][11] According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Scania measures between 19.689 and 23.58 kilometers in diameter and its surface has an albedo between 0.189 and 0.262.

[6][7][8] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1808 and a diameter of 21.63 kilometers based on an absolute magnitude of 10.8.
