11 Ursae Minoris b is an extrasolar planet, discovered on August 12, 2009. It is 390 light years away from Earth. It orbits its star, 11 Ursae Minoris every 516 (or 513) earth days. The planet's mass is estimated to be around 10.5 ± 2.47 MJ, though since the mass is at lower limit and since inclination is not known, the actual mass isn't known. The planet might be a brown dwarf, if the planets mass is 13 times that of Jupiter.
