K2-131 and Its Super-Earth
K2-131 is a star located 497 light-years away. It hosts one known planet. The star's reported mass estimate is 0.803 solar masses and its reported radius estimate is 0.76 solar radii, both smaller than the Sun's. Its reported temperature is 5120 K, cooler than the Sun's, and its age is 5.3 billion years.
The planet K2-131 b is a Super-Earth discovered by transit in 2017. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-131 b has a mass of 7.9 Earth masses and a radius of 1.69 Earth radii, both larger than Earth's. Its mean density is 9.02 g/cm³, 1.64 times Earth's. The planet completes an orbit in 0.369 days.
