Kepler-1820 b: A Neptune-Like World in a Distant System
Kepler-1820 is a star located 4650 light-years away, with a mass of 1.05 solar masses, a radius of 0.931 solar radii, and a temperature of 5840 K. One planet is known to orbit this host.
That planet, Kepler-1820 b, is Neptune-like and was discovered by transit in 2021. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness; repeated dips help establish orbital periods. The planet's orbital period is 31 days, and its radius is 3.12 Earth radii, a reported estimate larger than Earth's.
