Kepler-1789 and Its Neptune-Like Planet
Kepler-1789 is a star located 1990 light-years away. It has a mass of 0.939 solar masses and a radius of 0.893 solar radii, with a temperature of 5690 K. One planet orbits this host.
That planet is Kepler-1789 b, 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-1789 b completes an orbit every 80.2 days and has a radius of 2.83 Earth radii. That radius estimate is larger than Earth's.
