Kepler-990 and Its Two Known Planets
Kepler-990 is a star located 2620 light-years away. It has an age of 3.55 billion years, a mass of 1.05 solar masses, a radius of 1.08 solar radii, and a temperature of 5950 K. Two planets are known to orbit this host.
Both planets were discovered by transit in 2016. Kepler-990 b is Neptune-like, with a radius of 2.6 Earth radii and an orbital period of 9.92 days. Kepler-990 c is a Super-Earth, with a radius of 1.53 Earth radii and an orbital period of 0.538 days.
Among the listed planets, Kepler-990 b has the longest year by reported estimates, while Kepler-990 c has the shortest. Kepler-990 b also has the largest radius by reported estimates, and Kepler-990 c has the smallest. Each planet's reported radius estimate is larger than Earth's. 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.
