K2-35: A K-Type Dwarf with Two Transiting Planets

K2-35 is a K4 V star located 824 light-years away. Its mass is 0.76 solar masses, its radius is 0.72 solar radii, and its temperature is 4680 K, all of which are smaller or cooler than the Sun's corresponding values. Two planets are known to orbit this star.

K2-35 b and K2-35 c were both discovered by the transit method in 2016. K2-35 b is classified as Earth-like, with a reported radius of 1.32 Earth radii and an orbital period of 2.4 days. K2-35 c is a Super-Earth with a reported radius of 1.93 Earth radii and an orbital period of 5.61 days. Both planets' reported radii are larger than Earth's.

Among the listed planets, K2-35 b has the shortest year and the smallest radius, while K2-35 c has the longest year and the largest radius. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Repeated dips help establish orbital periods. Planet size classes compare radius with Earth's: an Earth-like planet stays within 1.5 times Earth's radius, while a Super-Earth reaches 2.5 times.
