Kepler-657 and Its Neptune-Like Planet

Kepler-657 is a star located 5520 light-years away. It has a mass of 1.01 solar masses and a radius of 1.01 solar radii, with a temperature of 5810 K and an age of 4.17 billion years. One planet is known to orbit this host.

That planet is Kepler-657 b, a Neptune-like world discovered by the transit method in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Kepler-657 b completes an orbit every 24.5 days and has a radius of 3.52 Earth radii, which is larger than Earth's. Its size places it within the Neptune-like class, which extends to 4 times Earth's radius.
