Kepler-250 and Its Three Planets

Kepler-250 is a star located 2480 light-years away. Its mass is 0.83 solar masses, its radius is 0.79 solar radii, and its reported temperature is 5100 K. Its age is 5.13 billion years. The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's. Three planets are known to orbit this host: Kepler-250 b, Kepler-250 c, and Kepler-250 d.

Kepler-250 b is an Earth-like planet discovered by transit in 2014. It completes an orbit every 4.15 days and has a radius of 1.13 Earth radii. Among the listed planets, it has the shortest year and the smallest radius.

Kepler-250 c is a Super-Earth discovered by transit in 2014. Its orbital period is 7.16 days, and its radius is 2.28 Earth radii. Among the listed planets, it has the second-shortest year and the largest radius.

Kepler-250 d is a Super-Earth discovered by transit in 2014. It orbits every 17.6 days and has a radius of 2.18 Earth radii. Among the listed planets, it has the longest year and the second-smallest radius.
