Artist's conceptAccording to a NASA press
release: “‘Planet-hunting astronomers have crossed an important threshold in planet detection, with the discovery of two planets that may be smaller in mass than Saturn. Of the 30 extrasolar planets around Sun-like stars detected previously, all have been the size of Jupiter or larger. The existence of these Saturn-sized
candidates suggests that many stars harbor smaller planets, in addition to the Jupiter-sized ones.”
