Kepler-1129 and Its Two Planets
Kepler-1129 is a star 3860 light-years away with 1 solar masses, 1 solar radii, a temperature of 5830 K, and an age of 4.07 billion years. Two planets are known to orbit it.
Both are Neptune-like planets discovered in 2016 by the transit method. Kepler-1129 b has a radius of 2.96 Earth radii and takes 24.3 days to orbit. Kepler-1129 c has a radius of 2.73 Earth radii and takes 76.5 days to orbit. Among the listed planets, Kepler-1129 b has the shortest year and the largest radius, while Kepler-1129 c has the longest year and the smallest radius. Both have reported radius estimates larger than Earth's.
