Huberta (minor planet designation: 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[2] 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.
