K2-184 b: An Earth-Like World Around a Cool Dwarf Star
K2-184 is a star located 247 light-years from Earth. It has a reported mass of 0.89 solar masses, a radius of 0.767 solar radii, and a temperature of 5240 K. Each of these estimates is smaller or cooler than the corresponding value for the Sun. One planet is known to orbit this star.
That planet is K2-184 b, an Earth-like world discovered in 2018 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. K2-184 b completes an orbit every 17 days. Its radius is 1.47 Earth radii, larger than Earth's, and this places it within the Earth-like size class, which covers planets up to 1.5 times Earth's radius.
