Kepler-1643 and Its Super-Earth
Kepler-1643 is a star 1110 light-years away with one known planet in orbit. The host star is 3.89 billion years old and has a mass of 0.92 solar masses, a radius of 0.88 solar radii, and a temperature of 5510 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The planet is Kepler-1643 b, a Super-Earth discovered by transit in 2016. 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. Kepler-1643 b orbits every 5.34 days and has a radius of 2.32 Earth radii, which is larger than Earth's. In size classification, a Super-Earth reaches 2.5 times Earth's radius.
