Kepler-687 b: A Neptune-Like World in a Distant System
Kepler-687 is a star located 2070 light-years away, and it hosts one known planet. The star is estimated to be 5.5 billion years old, with a mass of 0.77 solar masses, a radius of 0.73 solar radii, and a temperature of 4840 K. Its reported mass and radius are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The planet Kepler-687 b is Neptune-like, a size class that reaches four times Earth's radius. Its radius of 3.52 Earth radii is larger than Earth's, and it completes an orbit every 20.5 days. The planet was discovered by the transit method in 2016.
