About this world
K2-368 c is a super-Earth orbiting K2-368, an orange dwarf 674 light-years from Earth. It is about 1.4 times the size of Earth. It completes an orbit every 9.66 days at 0.081 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 659 K (386 °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 2022 by transit with K2. A planet crosses its star and dims it by a tiny, periodic fraction. K2-368 has 3 known planets; the others are K2-368 b and K2-368 d.
