In astrometry planet hunting one looks for a planet by looking for the &#8220;wobble&#8221; of a star as it moves across the sky.  This is contrast with the two other methods used to detect planets around stars, which use radial velocity or transits to detect the planets.  Now it seems that a team from JPL has used a series of measurements over 12 years to detect a Jupiter sized planet tugging on its star, VB 10.  The wobble in this case is a movement of about one sixth of an arcsecond per year.
