AN EXTENDED EXTRASOLAR PLANETARY SYSTEM, a star orbited by three satellites, has been mapped by two separate teams of astronomers, one using the Lick Observatory in California (http://www.physics.sfsu.edu/~gmarcy/planetsearch /upsand/upsand.html) and one using Harvard-Smithsonian's Whipple Observatory in Arizona. The innermost planet circling the star Upsilon Andromedae (44 light years from Earth) had been known previously but the discovery of its two siblings is new. The presence of the planets is inferred from irregularities in the star's light emission. The masses for the three planets (working outwards, 0.75, 2, and 4 Jupiter masses) and the orbital radii (0.06, 0.83, and 2.5 times the Earth-Sun distance) are puzzling since according to some theories a Jupiter-sized planet (much less three of them) should not have formed so close to a star. (The two groups of astronomers have submitted their findings to the Astrophysical Journal.)
