From Wikipedia, the free encyclopedia
126 Velleda is a main-belt asteroid. It is probably a rather typical, albeit sizable, S-type asteroid. This asteroid was named for Veleda, a priestess and prophet of the Germanic tribe of the Bructeri. It was discovered by Paul Henry on 5 November 1872, in Paris, France. It was his first credited discovery. He and his brother Prosper Henry discovered a total of 14 asteroids.
