But, NO, when it got just 2° warmer, its people would panic, try to make a sudden switch in energy use, and go extinct. It completes one orbit every 122 days and is 1.6 times larger than Earth. Planets more similar to Earth are not necessarily more habitable, since the ESI does not consider all factors necessary for habitability. The habitable zone around K-dwarf stars, the potential site for superhabitable planets. ESI: 0.83Kepler-62 e is a Super-Earth exoplanet that orbits in the inner habitable zone of its star, Kepler-62 (which is slightly smaller and cooler than our sun). Based on data from the Kepler mission, these super-habitable worlds may have conditions more suitable for sustaining life for a longer period of time than our planet. The usual assumption is that an orbit around a G-type star like the Sun would be the best place to find a habitable planet. 1.5 < Planet Radius ≤ 2.5 Earth radii or 5 < Planet Minimum Mass ≤ 10 Earth masses). In fact, at least four are within 30 light-years of our Sun, with the closest only 20 light-years away.
