Kepler-921 and Its Neptune-Like Planet
Kepler-921 is a star located 3050 light-years away. It is 4.27 billion years old, has a mass of 0.93 solar masses, and a radius of 0.91 solar radii. Its temperature is 5660 K. The star's reported mass estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.
One planet orbits Kepler-921. Kepler-921 b is a Neptune-like planet 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, and repeated dips help establish orbital periods. Kepler-921 b completes an orbit every 51.3 days. Its radius is 2.87 Earth radii, which is larger than Earth's.
