(300163) 2006 VW139 (provisional designation 2006 VW139, periodic comet designation 288P/2006 VW139) is a binary active asteroid and main-belt comet from the outer regions of the asteroid belt. The object was discovered by Spacewatch in 2006. Its binary nature was confirmed by the Hubble Space Telescope in September 2016.[5] Both primary and its minor-planet moon are similar in mass and size, making it a true binary system.[5] The components are estimated to measure 1.8 kilometers in diameter, orbiting each other at a wide separation of 104 kilometers every 135 days.[4][6][8]
