About this world
Kepler-386 b is a super-Earth orbiting Kepler-386, an orange dwarf 2.88 thousand light-years from Earth. It is about 1.4 times the size of Earth. It completes an orbit every 12.3 days at 0.096 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 651 K (378 °C): far too hot for liquid water on its surface. By the "cosmic shoreline", its star has probably stripped its atmosphere away, leaving bare rock.
It was discovered in 2014 by transit with Kepler. A planet crosses its star and dims it by a tiny, periodic fraction. Kepler-386 has 2 known planets; the others are Kepler-386 c.
