Valda (minor planet designation: 262 Valda) is a main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 3 November 1886 in Vienna.[3] The name was proposed by Bettina von Rothschild.[4]
Photometric observations of this asteroid from the Organ Mesa Observatory in Las Cruces, New Mexico, during 2010 gave a light curve with a period of 17.386 ± 0.001 hours and a brightness variation of 0.17 ± 0.02 magnitude.[2]
