10-μm radiometric data collected from Kitt Peak in 1975 gave a diameter estimate of 34 km.

[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] The result is double the 5.18-hour period reported in the JPL Small-Body Database.

[1] On 2028-Apr-05, Vala will pass 0.0276 AU (4,130,000 km; 2,570,000 mi) from asteroid 2 Pallas.
