About this world
Kepler-1322 c is a sub-Neptune orbiting Kepler-1322, a yellow, Sun-like star 4.4 thousand light-years from Earth. It is about 2.2 times the size of Earth. It completes an orbit every 6.46 days at 0.065 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 883 K (610 °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 2021 by transit with Kepler. A planet crosses its star and dims it by a tiny, periodic fraction. Kepler-1322 has 2 known planets; the others are Kepler-1322 b.
