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, Template:Lit), a prophetess in Norse paganism.[1] One observation of an 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.[2]
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.[4] The result is double the 5.18-hour period reported in the JPL Small-Body Database.[5]
