Planets of EPIC 220674823
EPIC 220674823 is a G-type star 798 light-years away with two known planets. The star's reported mass estimate is 0.93 solar masses and its radius estimate is 0.83 solar radii, both smaller than the Sun's. Its temperature is 5590 K, cooler than the Sun's, and its age is 5 billion years.
The two planets are EPIC 220674823 b, classified as a Super-Earth, and EPIC 220674823 c, classified as a Neptune-like planet. Both were discovered by the transit method in 2016, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness.
EPIC 220674823 b has a radius of 1.61 Earth radii and a mass of 7.54 Earth masses, both larger than Earth's. Its mean density is 10 g/cm³, 1.82 times Earth's. Its orbital period is 0.571 days, and among the listed planets this is the shortest year. It also has the smallest radius and the smallest reported mass among the listed planets.
EPIC 220674823 c has a radius of 2.71 Earth radii and a mass of 7.9 Earth masses, both larger than Earth's. Its mean density is 2.18 g/cm³, 0.396 times Earth's. Its orbital period is 13.3 days, and among the listed planets this is the longest year. It also has the largest radius and the largest reported mass among the listed planets.
