K2-368: A Cool Star with Three Small Worlds
K2-368 is a star located 674 light-years away, and it hosts three known planets. The star has a mass of 0.746 solar masses and a radius of 0.663 solar radii, and its temperature is 4660 K. Its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.
All three planets were discovered by transit in 2022. 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.
K2-368 b is classified as Earth-like. It has an orbital period of 5.03 days and a radius of 1.33 Earth radii, which is larger than Earth's. Among the listed planets, it has the shortest year and the smallest radius by reported estimates.
K2-368 c is also Earth-like, with an orbital period of 9.66 days and a radius of 1.36 Earth radii, larger than Earth's. Among the listed planets, it has the second-shortest year and the second-smallest radius by reported estimates.
K2-368 d is classified as a Super-Earth. Its orbital period is 20.2 days, and its radius is 1.95 Earth radii, larger than Earth's. Among the listed planets, it has the longest year and the largest radius by reported estimates.
