Three Earth-like planets discovered orbiting dwarf star
Story highlights Researchers have discovered three potentially habitable, Earth-like worlds orbiting a dwarf star The star and its planets are 40 light-years away in another star system CNN — For the first time, researchers have discovered three potentially habitable, Earth-like worlds orbiting an ultracool dwarf star 40 light-years away in another star system, according to a study published in the journal Nature. Stenzel This artist's impression shows an imagined view from the surface one of the three planets orbiting an ultracool dwarf star just 40 light-years from Earth that were discovered using the TRAPPIST telescope at ESO's La Silla Observatory. NASA Ames/SETI Institute/JPL-Caltech Scientists announced in June 2013 that three planets orbiting star Gliese 667C could be habitable. “It was only a 1% dip in light, but the specific pattern was a good sign of orbiting planets.” The planets are about the size of Earth and given the proximity of two of them to the dwarf star, they receive about four times the amount of radiation than we do from the sun, which suggests they are in the “habitable zone.” According to Burgasser, the “habitable zone,” determines how close a planet is to the star that it orbits and given the temperature of the planet based on that proximity, it could have water on the surface.
