| Three super-Earth-size planets found in 'habitable zone' Posted: 18 Apr 2013 11:29 AM PDT NASA's Kepler mission has discovered two new planetary systems that include three super-Earth-size planets in the "habitable zone," the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water. The Kepler-62 system has five planets; 62b, 62c, 62d, 62e and 62f. The Kepler-69 system has two planets; 69b and 69c. Kepler-62e, 62f and 69c are the super-Earth-sized planets. |
| New techniques allow discovery of smallest super-Earth exoplanets Posted: 18 Apr 2013 11:24 AM PDT New research has perhaps the smallest super-earth planet in its host star habitable zone. Kepler 62f is a small, probably rocky planet orbiting a sun-like star in the Lyra constellation. The planet is about 1.4 times the size of Earth, receives about half as much solar flux, or heat and radiation, as Earth and circles its star in 267.3 (Earth) days. |
| New Earth-like planets found orbiting a Sun-like star Posted: 18 Apr 2013 11:09 AM PDT A team of scientists has discovered two Earth-like planets in the habitable orbit of a Sun-like star. Using observations gathered by NASA's Kepler Mission, the team found five planets orbiting a Sun-like star called Kepler-62. Four of these planets are so-called super-Earths, larger than our own planet, but smaller than even the smallest ice giant planet in our Solar System. These new super-Earths have radii of 1.3, 1.4, 1.6, and 1.9 times that of Earth. In addition, one of the five was a roughly Mars-sized planet, half the size of Earth. |
