K2-355 and Its Planet

K2-355 is a star located 1630 light-years away. Its mass is 0.98 solar masses, smaller than the Sun's, and its radius is 0.941 solar radii, also smaller than the Sun's. Its reported temperature of 5570 K is cooler than the Sun's.

One planet is known to orbit this star. K2-355 b is a Super-Earth discovered by transit in 2021, meaning it was detected as it passed in front of its star and dimmed its light slightly. Its radius is 2.25 Earth radii, larger than Earth's, and its orbital period is 5.74 days, the time it takes to complete one orbit.
