K2-64: A Distant Star with One Known Planet
K2-64 is a star located 1630 light-years away. Its mass is 0.94 solar masses, its radius is 0.875 solar radii, and its temperature is 5390 K. Each of these values is smaller or cooler than the corresponding value for the Sun.
One planet is known to orbit K2-64. K2-64 b is classified as a Super-Earth, a size class that extends to 2.5 times Earth's radius. Its radius is 2.07 Earth radii, larger than Earth's. It completes an orbit every 6.53 days. The planet was discovered in 2016 by the transit method, in which a planet passing in front of its star from our viewpoint causes a small dip in observed brightness.
