About this world
K2-36 c is a sub-Neptune orbiting K2-36, an orange dwarf (type K2V) 358 light-years from Earth. It is about 3.2 times the size of Earth and holds 7.9 Earth masses. It completes an orbit every 5.34 days at 0.055 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 854 K (581 °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 2016 by transit with K2. A planet crosses its star and dims it by a tiny, periodic fraction. K2-36 has 2 known planets; the others are K2-36 b.
