    2002 VT130 is a classical Kuiper belt object (cubewano). It was discovered by Marc W. Buie at Kitt Peak Observatory on 7 November 2002.[2][4]

    Physical properties

    The object belongs to the cold classical population and is a binary. The satellite was discovered by K. S. Noll, W. M. Grundy, S. D. Benecchi, and H. A. Levison using Hubble Space Telescope in 2009. The apparent separattion from the primary was 2490 ± 80 km.[4] The estimated combined size of 2002 VT130 is about 324 km.[3]

    2002 VT130 shows significant photometric variability with the lightcurve amplitude of 0.21. This may indicate that 2002 VT130 binary is a result of a collision.[5]
