K2-342 b: A Super-Earth in Transit
K2-342 is a star 680 light-years away with a mass of 1.07 solar masses, a radius of 1.07 solar radii, and a temperature of 5890 K. Its reported radius estimate is larger than the Sun's. One planet orbits this host.
That planet is K2-342 b, a Super-Earth discovered by transit in 2021. 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. K2-342 b completes its orbit in 11.6 days. Its radius is 2.03 Earth radii, larger than Earth's. Size classes such as Super-Earth compare radius with Earth's, not composition.
