Kepler-1128 b: A Neptune-Like World in a Distant System
Kepler-1128 is a star located 3530 light-years away, and it hosts one known planet. The star's reported mass estimate is smaller than the Sun's at 0.94 solar masses, while its radius measures 0.91 solar radii. It is cooler than the Sun, with a temperature of 5540 K, and its age is 4.57 billion years.
The sole planet, Kepler-1128 b, is a Neptune-like world discovered by the transit method in 2016. Its reported radius estimate is 3.65 Earth radii, which is larger than Earth's and falls within the size range of Neptune-like planets, those reaching up to 4 times Earth's radius. Its orbital period is 61.6 days.
