First Multi-Planet System Discovered by Kepler

From the creator

NASA's Kepler Mission has discovered the first confirmed planetary system with more than one planet transiting the same star. The announcement of the discovery of the two planets, Kepler 9b and 9c, is based on seven months of observations. Kepler is monitoring more than 156,000 stars for subtle brightness changes as part of an ongoing search for Earth-size planets outside our solar system. Scientists designated the sun-like star Kepler-9.
