Kepler-550 and Its Lone Known Planet
Kepler-550 is a star located 1730 light-years away, and it has one known planet. The star is 4.68 billion years old, with a mass of 0.87 solar masses and a radius of 0.83 solar radii. Its temperature is 5320 K. The reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
The planet is Kepler-550 b, 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. Kepler-550 b has an orbital period of 8.6 days, the time it takes to complete one orbit. Its radius is 4.42 Earth radii, and this reported radius estimate is larger than Earth's. Kepler-550 b is classified as Jupiter-like.
