About this world
EPIC 249893012 c is a sub-Neptune orbiting EPIC 249893012, a yellow, Sun-like star (type G8IV/V) 1.05 thousand light-years from Earth. It is about 3.7 times the size of Earth and holds 15 Earth masses. It completes an orbit every 15.6 days at 0.13 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 990 K (717 °C): far too hot for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2020 by transit with K2. A planet crosses its star and dims it by a tiny, periodic fraction. EPIC 249893012 has 3 known planets; the others are EPIC 249893012 b and EPIC 249893012 d.
