Kepler-1020 b: A Super-Earth in a Distant System
Kepler-1020 is a star located 1350 light-years from Earth, and it hosts one known planet. The star is estimated to be 3.63 billion years old, with a mass of 0.87 solar masses and a radius of 0.8 solar radii. Its temperature is 5230 K. These reported estimates place the star's mass, radius, and temperature below the Sun's corresponding values.
The system's sole cataloged planet is Kepler-1020 b, a Super-Earth discovered by the transit method in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Kepler-1020 b completes an orbit every 96.9 days. Its radius is 2.28 Earth radii, making it larger than Earth.
