QS Virginis b is a circumbinary brown dwarf which orbits both the white dwarf and red dwarf stars in the QS Virginis system, located approximately 156 light years away in the constellation Virgo. This brown dwarf has at least 6.4 times the mass of Jupiter and takes 7.86 years to orbit the star at a semimajor axis of 4.2 AU. This brown dwarf was detected by eclipsing binary minima timing on November 13, 2009.
