Kepler-466 and Its Two Worlds

Kepler-466 is a star located 1730 light-years away. It hosts two planets. The star's reported mass estimate is larger than the Sun's, at 1.04 solar masses, and its radius is 1.05 solar radii. Its reported temperature is hotter than the Sun's at 5930 K, and its age is 3.47 billion years. Both planets were discovered by transit, the method in which a planet passing in front of its star causes a small dip in observed brightness, and both were reported in 2016.

Kepler-466 c is an Earth-like planet with a radius of 1.25 Earth radii, making it the smallest radius among the listed planets. Its year is 3.71 days, the shortest among the listed planets. Kepler-466 b is a Neptune-like planet with a radius of 2.85 Earth radii, the largest among the listed planets, and a year of 51.1 days, the longest among the listed planets. Its reported radius estimate is larger than Earth's, as is Kepler-466 c's.
