K2-396: A Sun-Like Star and Its Two Transiting Planets

K2-396 is a G-type star located 896 light-years away, with a mass of 0.954 solar masses, a radius of 0.92 solar radii, and a temperature of 5240 K. Its radius is smaller than the Sun's, and its temperature is cooler. Two planets orbit this star, both discovered by transit in 2022.

K2-396 b is a Super-Earth with an orbital period of 0.674 days and a radius of 1.58 Earth radii, larger than Earth's. K2-396 c is Neptune-like, with an orbital period of 25.8 days and a radius of 3.12 Earth radii, also larger than Earth's.

Among the listed planets, K2-396 b has the shortest year and the smallest radius, while K2-396 c has the longest year and the largest radius.
