Kepler-1021 is a star 2640 light-years away with one planet in its system. The star is 4.68 billion years old, has 0.89 solar masses and 0.86 solar radii, and has a temperature of 5430 K. Its mass, radius, and temperature are all smaller or cooler than the Sun's.
The planet Kepler-1021 b is a Super-Earth discovered by transit in 2016. It orbits every 13.5 days and has 2.33 Earth radii, larger than Earth's radius. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness; repeated dips help establish orbital periods.
