Kepler-987 and Its Neptune-Like Planet
Kepler-987 is a star located 2980 light-years away. It has one planet. The star is 2.45 billion years old, with a mass of 0.97 solar masses and a radius of 0.91 solar radii, which is smaller than the Sun's. Its temperature is 5640 K, cooler than the Sun's.
The planet Kepler-987 b was discovered in 2016 by the transit method. 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, and Kepler-987 b's orbital period is 105 days. It is a Neptune-like planet, a size class that reaches 4 times Earth's radius. Its radius is 3.26 Earth radii, larger than Earth's.
