K2-195: A Distant Star With Two Neptune-Like Planets

K2-195 is a star located 1030 light-years away, and two planets have been found in orbit around it. The host star has a mass of 1.03 solar masses, a radius of 0.994 solar radii, and a temperature of 5750 K.

Both planets are Neptune-like and were discovered by the transit method in 2018. K2-195 b has an orbital period of 15.9 days and a radius of 3.13 Earth radii. K2-195 c has an orbital period of 28.5 days and a radius of 2.58 Earth radii. Among the listed planets, K2-195 b has the shortest year by reported estimates, and K2-195 c has the longest year. K2-195 c also has the smallest radius by reported estimates, while K2-195 b has the largest.
