17 New Planets Including Earth-Sized World Discovered by Astronomy Student

University of British Columbia astronomy student Michelle Kunimoto has discovered 17 new planets, including a potentially habitable, Earth-sized world, by combing through data gathered by NASA’s Kepler mission.
Over its original four-year mission, the Kepler satellite looked for planets, especially those that lie in the “Habitable Zones” of their stars, where liquid water could exist on a rocky planet’s surface.
The new findings, published in The Astronomical Journal, include one such particularly rare planet. Officially named KIC-7340288 b, the planet discovered by Kunimoto is just 1 ½ times the size of Earth — small enough to be considered rocky, instead of gaseous like the giant planets of the Solar System and in the habitable zone of its star.
