(300163) 2006 VW 139 , also called 288P / 2006 VW 139 or 288P for short , is a double asteroid of the asteroid belt and a main belt comet . It consists of two parts, each about one kilometer in diameter, which orbit each other on a strongly elliptical orbit at a distance of about 100 km. The object belongs to the group of atypical asteroids with comet-like features such as coma and tail . It is the only known active double asteroid with such features.
Scientists at the Max Planck Institute for Solar System Research in Göttingen became aware of the object in the asteroid belt between Mars and Jupiter back in 2011 . When it approached Earth to around two hundred million kilometers in September 2016, they had it observed with the Hubble space telescope . When evaluating the data, the researchers recognized two separate celestial bodies. They assume that the asteroid broke up into its present two parts about 5000 years ago due to its own rotation.
