The Kepler-838 System
Kepler-838 is a star located 3600 light-years away. It has one known planet. The host star is 4.17 billion years old and contains 0.98 solar masses. Its radius is 0.96 solar radii, and its temperature is 5770 K.
Kepler-838 b is a Neptune-like planet discovered in 2016 by the transit method, which detects the small dip in a star's brightness when a planet passes in front of it. The planet completes an orbit every 15.7 days. Its radius is 2.73 Earth radii, a reported estimate larger than Earth's.
