About this world
EPIC 212424622 b is a sub-Neptune orbiting EPIC 212424622, a yellow, Sun-like star 2 thousand light-years from Earth. It is about 2.2 times the size of Earth. It completes an orbit every 18.1 days at 0.14 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 827 K (554 °C): far too hot for liquid water on its surface. By the "cosmic shoreline", its star has probably stripped its atmosphere away, leaving bare rock.
It was discovered in 2019 by transit with K2. A planet crosses its star and dims it by a tiny, periodic fraction.
