About this world
Kepler-504 b is a super-Earth orbiting Kepler-504, a cool red dwarf 323 light-years from Earth. It is about 1.6 times the size of Earth. It completes an orbit every 9.55 days at 0.065 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 374 K (101 °C): too cold 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 2016 by transit with Kepler. A planet crosses its star and dims it by a tiny, periodic fraction.
