K2-308 b: A Jupiter-like World in a Distant System
K2-308 is a star located 4290 light-years away. It has a mass of 1.09 solar masses, a radius of 1.24 solar radii, and a temperature of 6100 K. Its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet orbits this host.
That planet is K2-308 b, a Jupiter-like world discovered by transit in 2019. 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. K2-308 b completes an orbit every 3.39 days and has a radius of 9.92 Earth radii. Its reported radius estimate is larger than Earth's.
