Vala (minor planet designation : 131 Vala ) is an inner main-belt asteroid . It was discovered by C. H. F. Peters on 24 May 1873, and derives its name from völva vǫlva , lit. ' staff bearer ' ), a prophetess in Norse paganism .[4] occultation of a star by Vala is from Italy (26 May 2002). 10-μm radiometric data collected from Kitt Peak in 1975 gave a diameter estimate of 34 km.[5]
In the Tholen classification system, it is categorized as an SU-type asteroid , while the Bus asteroid taxonomy system lists it as a K-type asteroid .[3] Photometric observations of this asteroid during 2007 at the Organ Mesa Observatory in Las Cruces, New Mexico were used to create a "nearly symmetric bimodal" light curve plot. This showed a rotation period of 10.359 ± 0.001 hours and a brightness variation of 0.09 ± 0.02 magnitude during each cycle.[6] JPL Small-Body Database .[1]
On 2028-Apr-05, Vala will pass 0.0276 AU km mi 2 Pallas .[7]
