Kepler-386: A Distant Star With Two Known Planets
Kepler-386 is a star located 2880 light-years away, and it hosts two known planets. The star is estimated to be 4.68 billion years old. Its mass is 0.82 solar masses, its radius is 0.78 solar radii, and its temperature is 5100 K. Its reported mass estimate is smaller than the Sun's, its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.
Both planets were discovered in 2014 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Kepler-386 b is an Earth-like planet with an orbital period of 12.3 days and a radius of 1.39 Earth radii. Kepler-386 c is a Super-Earth with an orbital period of 25.2 days and a radius of 1.58 Earth radii.
Among the listed planets, Kepler-386 b has the shortest year by reported estimates, at 12.3 days, and the smallest radius by reported estimates, at 1.39 Earth radii. Kepler-386 c has the longest year by reported estimates, at 25.2 days, and the largest radius by reported estimates, at 1.58 Earth radii.
