Kepler-1638 is a G4V-type star located 4,973 light years away in the constellation of Cygnus. [1] At least one exoplanet has been found orbiting the star: Kepler-1638b. [2] [3] [4] [5] [6] This planet is a potentially habitable Super-Earth with an Earth Similarity Index of 0.76. As of January 2021, Kepler-1638 is the farthest star with a known potentially habitable exoplanet. [7]
