Recent Events in Science Earth-Size Planets Common in Galaxy: Perhaps 17 Percent of Sun-Like Stars Have Earth-Size Planets Within the Orbit of Mercury Read All About It! 3/01/ htm An analysis of the first three years of data from NASA's Kepler mission, which already has discovered thousands of potential exoplanets, contains good news for those searching for habitable worlds outside our solar system. It shows that 17 percent of all sun-like stars have planets one to two times the diameter of Earth orbiting close to their host stars, according to a team of astronomers from the University of California, Berkeley, and the University of Hawaii at Manoa. This estimate includes only planets that circle their stars within a distance of about one- quarter of Earth's orbital radius -- well within the orbit of Mercury -- that is the current limit of Kepler's detection capability. Further evidence suggests that the fraction of stars having planets the size of Earth or slightly bigger orbiting within Earth-like orbits may amount to 50 percent.
