Kepler-1681 b: A Neptune-like World in a Distant System
Kepler-1681 is a star located 2470 light-years away, with a reported mass of 0.724 solar masses and a radius of 0.759 solar radii. Its reported temperature is 5510 K. This star's reported mass estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.
One planet orbits this host: Kepler-1681 b, a Neptune-like world discovered by transit in 2020. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Kepler-1681 b completes an orbit every 69.9 days, and its radius measures 2.55 Earth radii, which is larger than Earth's. In size classification, a Neptune-like planet reaches four times Earth's radius.
