In May of 2009 astronomers from [[NASA|NASA's]] [[Jet Propulsion Laboratory]], [[Pasadena]], [[California]] announced a planet, '''VB 10b''' orbiting the nearby [[red dwarf]] star [[VB 10]] . They used the {{convert|200|in|m|abbr=on}} [[Hale telescope]] at the [[Palomar Observatory]] to detect this planet using the [[Methods_of_detecting_extrasolar_planets#Astrometry|astrometry method]]. If confirmed, this will be the first [[extrasolar planet]] to be discovered using this method.<ref name="announce">{{cite web |

VB10b is reported to be a [[gas giant]] orbiting the star [[VB 10]] in the [[constellation]] of [[Aquila (constellation)|Aquila]]. It is reported to be approximately six times the mass of [[Jupiter]] and is about 20 [[light years]] away from Earth.<ref name="announce" /><ref>{{cite news|url=http://www.newscientist.com/article/dn17208-exoplanet-found-by-measuring-stars-sideways-shift.html|title=Exoplanet found by measuring star's sideways shift |last= McKee|first=Maggie |date=28 May 2009|publisher=New Scientist}}</ref> |

==Past claims based on astrometry== |
|||
This is not the first extrasolar planet claimed to be found by astrometry. In 1969 [[Peter Van de Kamp]] claimed that a planet was orbiting [[Barnard's Star]]. In 1996 a claim of planets orbiting the nearby star [[Lalande 21185]] appeared in the popular press. Further observations of those stars showed both claims to be false.<ref name="sky">{{cite web |
