THE EXTRASOLAR PLANET PARADE continues with the discovery of two new planets with unique features. As before, astronomers Geoffrey Marcy (San Francisco State) and Paul Butler (Anglo-Australian Observatory) have inferred the presence of the planets from their observed influence on the companion star. One of the new objects orbits its star (HD187123) in a mere three days in an orbit 9 times closer than Mercury's around our sun. The other new planet has a very Earth-like orbit of 437 days around star HD21027. This comes as a reassurance to those who were beginning to wonder whether Earth was an anomaly; all previously discovered extrasolar planets have had orbits much smaller or much larger than Earth's.
