About this world
K2-47 b is a super-Earth orbiting K2-47, an orange dwarf 1.14 thousand light-years from Earth. It is about 1.9 times the size of Earth. It completes an orbit every 31.6 days at 0.18 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 504 K (231 °C): far too hot for liquid water on its surface. By the "cosmic shoreline", it has likely held on to an atmosphere.
It was discovered in 2016 by transit with K2. A planet crosses its star and dims it by a tiny, periodic fraction.
