Team finds 2 solar systems, one with 3 Earth-sized planets
Using data from NASA's Kepler Space Telescope, Spain-based astronomers have announced the discovery of two new planetary systems, with one of them hosting three Earth-sized planets. The first discovery involved a red dwarf star 160 light-years from Earth while other red dwarf had two 'super-Earths' about twice the size of the Earth, having surface temperatures over 3,000 ÂºC, said researchers.
