K2-387 b: A Jupiter-Like Planet in a Distant System
K2-387 is a star located 869 light-years away, and it hosts one known planet. The star has a reported mass estimate of 0.57 solar masses, smaller than the Sun's, and a reported radius estimate of 0.585 solar radii, also smaller than the Sun's. Its reported temperature is 3570 K, cooler than the Sun's.
The planet K2-387 b is classified as Jupiter-like, meaning its radius exceeds 4 times Earth's radius. Its reported radius estimate is 7.32 Earth radii, larger than Earth's. It completes one orbit every 28.7 days.
K2-387 b was discovered by the transit method, in which a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Repeated dips help establish orbital periods.
