Astronomers looking for planets encircling stars outside our solar system—known as extrasolar planets, or exoplanets—are claiming the first planetary detection from a technique known as astrometry, which tracks the location of stars in the sky with great precision.
Astrometric observations of a nearby star called VB 10 revealed a telltale motion in the star's position caused by the gravitational pull of its companion planet, dubbed VB 10b. VB 10 and its planet are an astronomical odd couple: the star is one of the least massive known, whereas the planet itself is some six times the mass of Jupiter. In contrast to the solar system, where the sun is some 10 times the diameter of the largest planet, VB 10 and VB 10b have roughly the same width.
