Kepler-224 and Its Four Planets
Kepler-224 is a star located 2550 light-years away. It is 2.29 billion years old and has a mass of 0.78 solar masses, a radius of 0.71 solar radii, and a temperature of 5090 K. Its reported mass estimate is smaller than the Sun's, its reported radius estimate is smaller than the Sun's, and its temperature is cooler than the Sun's. Four planets orbit this host: Kepler-224 b, Kepler-224 c, Kepler-224 d, and Kepler-224 e. All four were discovered by transit in 2014.
Kepler-224 b is an Earth-like planet with an orbital period of 3.13 days and a radius of 1.39 Earth radii. Its reported radius estimate is larger than Earth's. Among the listed planets, it has the shortest year and the smallest radius by reported estimates.
Kepler-224 c is a Neptune-like planet with an orbital period of 5.93 days and a radius of 3.12 Earth radii. Its reported radius estimate is larger than Earth's. Among the listed planets, it has the second-shortest year and the largest radius by reported estimates.
Kepler-224 d is a Super-Earth with an orbital period of 11.3 days and a radius of 2.3 Earth radii. Its reported radius estimate is larger than Earth's. Among the listed planets, it has the second-longest year and the second-largest radius by reported estimates.
Kepler-224 e is a Super-Earth with an orbital period of 18.6 days and a radius of 1.97 Earth radii. Its reported radius estimate is larger than Earth's. Among the listed planets, it has the longest year and the second-smallest radius by reported estimates.
