Planet Kepler-1889 b and Its Star
Kepler-1889 is a star located 4550 light-years away with one planet in orbit. The host star has a reported mass estimate of 0.853 solar masses, a radius of 0.817 solar radii, and a temperature of 5640 K. Its mass estimate is smaller than the Sun's.
The planet, Kepler-1889 b, is a Neptune-like world discovered by the transit method in 2021. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Kepler-1889 b has an orbital period of 37.3 days and a radius of 2.94 Earth radii, which is larger than Earth's.
