Astronomers have discovered an extra-solar planet of about three earth masses orbiting a star with a mass so low that its core may not be massive enough to maintain nuclear reactions. The planet, referred to as MOA-2007-BLG-192Lb, establishes a record for the lowest mass planet to orbit a normal star.
