K2-44: A Distant Star with a Super-Earth
K2-44 is a star located 1550 light-years away. It has a mass of 1.04 solar masses, a radius of 1.66 solar radii, and a temperature of 5800 K. Its reported radius estimate is larger than the Sun's. One planet is known to orbit this host.
That planet is K2-44 b, a Super-Earth discovered by the transit method in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. K2-44 b completes an orbit every 5.66 days. Its radius is 2.43 Earth radii, larger than Earth's.
