Kepler-118: A Distant Star With Two Known Planets
Kepler-118 is a star located 1870 light-years away, and two planets have been reported in orbit around it. The host star is estimated to be 4.68 billion years old, with a mass of 0.85 solar masses and a radius of 0.81 solar radii. Its reported temperature is 5230 K. The star's reported mass estimate, radius estimate, and temperature are all smaller or cooler than the Sun's.
Both planets were discovered by the transit method in 2014. Kepler-118 b is classified as a Super-Earth, with a radius of 1.96 Earth radii and an orbital period of 7.52 days. Kepler-118 c is a Jupiter-like planet with a radius of 7.68 Earth radii and an orbital period of 20.2 days.
Among the listed planets, Kepler-118 b has the shortest orbital period and the smallest radius by reported estimates. Kepler-118 c has the longest orbital period and the largest radius by reported estimates. Both planets' reported radius estimates are larger than Earth's.
