Kepler-1166 and Its Super-Earth
Kepler-1166 is a star located 2070 light-years from Earth, and it hosts one known planet. The star is estimated to be 4.9 billion years old, with a mass of 0.9 solar masses and a radius of 0.86 solar radii. Its temperature is 5450 K. Each of these reported stellar estimates is smaller or cooler than the corresponding value for the Sun.
The planet, Kepler-1166 b, was discovered in 2016 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Repeated dips help establish the planet's orbital period. Kepler-1166 b completes one orbit every 33.2 days and has a radius of 1.69 Earth radii, larger than Earth's. Its size class is Super-Earth.
