    (508869) 2002 VT130 is a trans-Neptunian object and binary system from the cubewano population in the Kuiper belt, located in the outermost region of the Solar System. It was first observed by American astronomer Marc Buie at Kitt Peak Observatory on 7 November 2002.[2][5] The primary measures approximately 324 kilometers in diameter.[6]

    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 separation from the primary was 2490 ± 80 km.[5] The estimated combined size of 2002 VT130 is about 324 km.[6]

    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.[7]
