Kepler-871 and Its Neptune-Like Planet
Kepler-871 is a star 6450 light-years away with one known planet. The host star is 3.47 billion years old, with a mass of 1.11 solar masses and a radius of 1.14 solar radii. Its temperature is 5990 K, making it hotter than the Sun. The star's reported mass and radius estimates are both larger than the Sun's.
The planet Kepler-871 b was 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. Kepler-871 b orbits its star every 22 days. With a radius of 3.74 Earth radii, the planet's reported radius estimate is larger than Earth's, placing it in the Neptune-like size class.
