About this world
K2-384 e is a super-Earth orbiting K2-384, a cool red dwarf (type M4V) 270 light-years from Earth. It is about 1.3 times the size of Earth. It completes an orbit every 9.72 days at 0.062 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 383 K (110 °C): too cold for liquid water on its surface. By the "cosmic shoreline", it has likely held on to an atmosphere.
It was discovered in 2022 by transit with K2. A planet crosses its star and dims it by a tiny, periodic fraction. K2-384 has 5 known planets; the others are K2-384 b, K2-384 c, K2-384 d and K2-384 f.
