CoRoT-15 is an eclipsing binary star system about 4,500 light-years (1,400 parsecs) away in the constellation Monoceros, discovered by the CoRoT space telescope in 2010. It consists of an F7V star and an orbiting brown dwarf companion, which was one of the first transiting brown dwarfs to be discovered.[4]
