Kepler-1649c
Kepler-1649c is an Earth-sized exoplanet, likely rocky, orbiting within the habitable zone of the red dwarf star Kepler-1649, the outermost planet of the planetary system discovered by "Kepler’s" space telescope. It is located about away from Earth, in the constellation of Cygnus. 

Kepler-1649c orbits its star a
distance of from its host star with an orbital period of roughly 19.53 days, has a mass 1.2x times that of Earth, and has a radius of around 1.02 times that of Earth. Based on its mass and radius, it is likely a terrestrial planet, though its proximity to its star means it may likely be tidally locked. Kepler-1649c is estimated to receive about quarters of the amount of radiation from its host star as Earth does from the Sun.

In 2017, Jeff Coughlin, the director of SETI's K2 Science Office, described it as the most "similar planet to Earth" found so far by the Kepler Space Telescope. The planet was originally deemed a false positive by Kepler's . The published its recovery on April 15, 2020. Its first scientific description was published in "The Astrophysical Journal Letters", with first author Andrew Vanderburg, in April 2020.
