Kepler-1897 b: A Neptune-Like World
Kepler-1897 is a single known star located 3210 light-years from Earth, and it hosts one planet. The star has a reported mass of 0.857 solar masses and a radius of 0.78 solar radii, both smaller than the Sun's corresponding values. Its temperature of 5170 K is cooler than the Sun's.
The planet Kepler-1897 b is classified as Neptune-like and was discovered by the transit method in 2021, when it passed in front of its star from our viewpoint. It completes an orbit every 24.2 days and has a radius of 2.81 Earth radii, making it larger than Earth.
