126 Velleda is a Main belt asteroid. It is probably a rather typical, albeit sizable, S-type asteroid. It was discovered by Paul Henry on November 5, 1872 in Paris, France. It was his first credited discovery. He and his brother Prosper Henry discovered a total of 14 asteroids.
This asteroid rotates once every 5 hours, 8 hours and 44 minutes. During each rotation the light curve varies by 0.22 magnitudes.[2]
