Hubble Makes Precise Measure Of Extrasolar World's True Mass

Summary:
NASA Hubble Space Telescope's crisp view has allowed an international team of astronomers to apply a previously unproven technique (astrometry) for making a precise measurement of the mass of a planet outside our solar system. The Hubble results place the planet at 1.89 to 2.4 times the mass of Jupiter, our solar system's largest world. Previous estimates, about which there are some uncertainties, place the planet's mass between 1.9 and 100 times that of Jupiter's.
