Kepler-977 and Its Neptune-Like Planet
Kepler-977 is a star 1860 light-years away with one known planet. The host star is 4.57 billion years old and has a mass of 0.87 solar masses, a radius of 0.83 solar radii, and a temperature of 5320 K, all smaller or cooler than the Sun.
The system's only cataloged planet is Kepler-977 b, a Neptune-like world detected by transit in 2016. It orbits every 26.9 days and has a radius of 2.62 Earth radii. Under the size classes used here, that radius is larger than Earth's and within the range of Neptune-like planets, which reach up to 4 times Earth's radius.
