K2-24: A Sun-Like Star and Its Two Jupiter-Like Planets
K2-24 is a G3 star located 556 light-years away. Its reported mass estimate is 1.12 solar masses and its radius estimate is 1.21 solar radii, both larger than the Sun's. The star is 5.1 billion years old and has a temperature of 5740 K. Two planets orbit this host.
Both planets were discovered by transit in 2016, a method that detects the small dip in a star's brightness when a planet crosses in front of it from our viewpoint.
K2-24 b is a Jupiter-like planet with a radius of 5.64 Earth radii, a mass of 20.6 Earth masses, and an orbital period of 20.9 days. Among the listed planets, it has the shortest year by reported estimates, the smallest radius, and the largest reported mass. Its mean density is 0.633 g/cm³, 0.115 times Earth's.
K2-24 c is also Jupiter-like, with a radius of 7.93 Earth radii, a mass of 16.4 Earth masses, and an orbital period of 42.3 days. Among the listed planets, it has the longest year by reported estimates, the largest radius, and the smallest reported mass. Its mean density is 0.181 g/cm³, 0.0329 times Earth's.
Both planets' reported radius and mass estimates are larger than Earth's.
