An Earth-like planet orbiting a nearby star in the Cygnus constellation was recently discovered by NASA. It is approximately 500 light-years from Earth and has been dubbed, Kepler-186f.
The Goldilocks zone, is the region around a star with sufficient atmospheric pressure that can support liquid water, which is the primary factor for life. Kepler-186f falls within this Goldilocks zone.
“We know of just one planet where life exists – Earth. When we search for life outside our solar system we focus on finding planets with characteristics that mimic that of Earth,” said Elisa Quintana, research scientist at the SETI Institute at NASA’s Ames Research Center in Moffett Field, Calif., and lead author of the paper published today in the journal Science. “Finding a habitable zone planet comparable to Earth in size is a major step forward.”
The nearby star to Kepler-186f has half the mass and size as Earth’s Sun and likely only emits about one-third of the energy. Kepler-186f orbits its star once every 130 days.[WATCH SHORT VIDEO](https://youtu.be/Zld7Lrvjyrs)
