Experts: Exoplanet could be smallest ever found (AP)

August 24th, 2010

This artistâ??s impression made available by the European Southern Observatory Tuesday, Aug. 24, 2010, shows the remarkable planetary system around the Sun-like star HD 10180. Observations with the HARPS spectrograph, attached to ESOâ??s 3.6-metre telescope at La Silla, Chile, have revealed the definite presence of five planets and evidence for two more in orbit around this star. This system is similar to the Solar System in terms of number of planets and the presence of a regular pattern in the sizes of the orbits. If confirmed the closest planet detected would be the lightest yet known outside the Solar System, with a mass that could be only about 1.4 times that of the Earth. (AP Photo/ESO, L. Calcada) ** EDITORIAL USE ONLY **AP - Scientists say they’ve identified a sun-like star with as many as seven different planets — including one that might be the smallest ever found outside the solar system.
