10.49[1] | |
771 Libera, provisional designation 1913 TO, is a metallic asteroid from the middle region of the asteroid belt, about 29 kilometers in diameter. It was discovered by Austrian astronomer Joseph Rheden at the Vienna Observatory in Austria, on 21 November 1913.[12]
Description
The metallic
rotation period of 5.892±0.002 hours with a brightness variation of 0.57 magnitude.[8] The result concurs with several previous observations, including a photometric analysis conducted over a twelve-year interval.[9][10][11]
According to the surveys carried out by the Infrared Astronomical Satellite,
albedo of 0.13 and 0.14, respectively, while the Collaborative Asteroid Lightcurve Link publishes a slightly lower figure of 0.12 from an alternative result of the Supplemental IRAS Minor Planet Survey.[4]
The minor planet was named by Mrs. Hedwig Rheden in honor of a friend of the discoverer.[3]
