Earth Like World

Located approximately 500 light-years away in the constellation Cygnus is the most Earth-like planet yet. Researchers discovered that this newly found world is the first of its size in a Goldilocks zone where water could pool in liquid form. It’s officially called Kepler-186f, and it obscures 400 photons of starlight out of every million as it transits its parent star, repeating the cycle every 130 days.

“Kepler-186f is significant because it is the first exoplanet that is the same temperature and the same size (well, ALMOST!) as the Earth. Previously, the exoplanet most like Earth was Kepler-62f, but Kepler-186f is significantly smaller. Now we can point to a star and say, ‘There lies an Earth-like planet,'” says David Charbonneau, who works with the Harvard-Smithsonian Center for Astrophysics.
