Van Biesbroeck's Star

In 2009 a team at the Jet Propulsion Laboratory made the controversial claim that they'd discovered a planet through astrometry around a tiny star known in catalogs as VB 10 and more eloquently (but less pronounceably) as Van Biesbroeck's Star. You can read more about that reported planetary system on astronomer Greg Laughlin's blog here:
VB 10b

Few of the planets discovered have ever been seen, and VB 10b, assuming it's really there, is one of an even rarer set of planets, those discovered by careful observation of their parent stars' position. Clearly this is an unusual system, and in order to sling Van Biesbroeck's Star far enough to be seen from Earth VB 10b has to weigh in at more than three times the mass of Jupiter, about a tenth of the mass of its anchoring star. Clearly this is a planet on the verge of becoming a star and a star that barely sustains fusion. Even if the discovery turns out to be spurious it's exciting to think that such places are really out there. As Laughlin points out, long after the rest of the Milky Way has gone dim places like VB 10 will shine on as they savor their nuclear fuel slowly for the long haul. It's nice to know there will be some light nearby long after the Sun goes dim.
