Study: Habitable Zone Exoplanets Kepler-62f and Kepler-186f Have Stable Climate, Regular Seasons

[kevindavis007]

New research from the Georgia Institute of Technology and the Harvard-Smithsonian Center for Astrophysics suggests that exoplanets Kepler-62f and Kepler-186f — both of which reside in the habitable zone around their host stars — have very stable axial tilts, much like the Earth, making it likely that each has regular seasons and a stable climate.


Kepler-62f is the outermost planet among five exoplanets orbiting a single star, Kepler-62, which is approximately 1,200 light-years away toward the constellation Lyra.

The planet orbits its host star every 267 days, is 1.4 times bigger than Earth and is likely a terrestrial or ocean-covered world.

Kepler-62f was the most Earth-like exoplanet until astronomers noticed Kepler-186f in 2014.

Kepler-186f is part of the five-planet system. It is about 1.17 times the radius of Earth, but its mass, composition and density remain a mystery.
