Exoplanetary Scratchpad

Contains the smallest planet in the habitable zone around a star at the time of its discovery by Kepler. The first around a sun-like star at Earth-like distances that is not probably tidally locked. The first potentially habitable planet confirmed (transits confirmed on other telescopes). Orbits around a sun-like star about every 290 days. It is about 2.4 times the radius of Earth. Its mass is difficult to measure and may be beyond the ability of modern telescopes (Keck will give it a try), so it has not been confirmed to be rocky yet (some planets the same size are either). It was the first of 54 habitable zone planet candidates to be independently confirmed. Depicted in art as blue with green clouds, the Scientific Exoplanets Renderer did not compute that it was habitable though. Its surface temperature is 76F, similar to a spring day on Earth.
