About this world
EPIC 212737443 c is a sub-Neptune orbiting EPIC 212737443, an orange dwarf (type K3) 1.1 thousand light-years from Earth. It is about 2.7 times the size of Earth. It completes an orbit every 65.5 days at 0.28 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 316 K (43 °C): too cold for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2019 by transit with K2. A planet crosses its star and dims it by a tiny, periodic fraction. EPIC 212737443 has 2 known planets; the others are EPIC 212737443 b.
