Super-earth around K2-216
It is 1.75 times Earth's radius, closest in size to Earth, and 8.0 times Earth's mass, at 8.20 g/cm3, denser than Earth. A year there lasts 2.17 days, on an orbit 14 times closer to its star than Mercury is to the Sun. Its equilibrium temperature is 1103 K, hot enough to melt lead. The host star K2-216 runs at 4503 K with 0.70 times the Sun's mass.

What the dip tells you
The depth of the dip is the ratio of the two discs, so the radius follows.

:NOTE
Found by K2 in 2018, the second life of the Kepler spacecraft after two of its reaction wheels failed and it could no longer hold a fixed stare.

:NOTE
The size came from a crossing, the mass did not. That pairing is uncommon and it is what lets anyone say whether this is rock or gas.
