Kepler-1457 and Its Super-Earth
Kepler-1457 is a star located 2900 light-years from Earth. It has one known planet. The host star is 3.72 billion years old, with a mass of 1.01 solar masses, a radius of 1.01 solar radii, and a temperature of 5870 K. Solar masses and radii compare stellar mass and radius with the Sun.
The planet Kepler-1457 b is a Super-Earth, a size class that reaches 2.5 times Earth's radius. It 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 orbital periods. Kepler-1457 b orbits its star every 51.1 days and has a radius of 1.99 Earth radii, larger than Earth's.
