Kepler-133 and Its Two Planets

Kepler-133 is a star 2130 light-years away with two planets orbiting it. The host star is 7.59 billion years old and has a mass of 1.04 solar masses, a radius of 1.32 solar radii, and a temperature of 5730 K. Its reported radius estimate is larger than the Sun’s.

The two planets were both discovered by transit in 2014. Kepler-133 b is a Super-Earth with an orbital period of 8.13 days and a radius of 1.76 Earth radii. Kepler-133 c is Neptune-like and has an orbital period of 31.5 days and a radius of 2.84 Earth radii. Among the listed planets, Kepler-133 b has the shortest year and the smallest radius, while Kepler-133 c has the longest year and the largest radius. Each planet’s reported radius estimate is larger than Earth’s.
