260 Huberta is a large asteroid orbiting near the outer edge of the Main belt. It is dark and rich in carbon.
It belongs to the Cybele group of asteroids and may have been trapped in a 4:7 orbital resonance with Jupiter.
It was discovered by Johann Palisa on 3 October 1886 in Vienna and was named after Saint Hubertus.
