Urda (minor planet designation : 167 Urda ) is a main-belt asteroid that was discovered by German-American astronomer Christian Heinrich Friedrich Peters on August 28, 1876, in Clinton, New York , and named after Urd , one of the Norns in Norse mythology . In 1905, Austrian astronomer Johann Palisa showed that the asteroid varied in brightness.[2]
Photometric observations of this asteroid at the Palmer Divide Observatory in Colorado Springs, Colorado , during 2007–8 gave a light curve with a period of 13.06133 ± 0.00002 hours.[3] S-type asteroid is a member of the Koronis family of asteroids that share similar orbital elements .[4]
In 2002, a diameter estimate of 37.93 ± 3.17 km was obtained from the Midcourse Space Experiment observations, with an albedo of 0.2523 ± 0.0448.[5]
A stellar occultation by Urda was observed from Japan on July 23, 2001.[6]
