About this world
Kepler-90 i is a super-Earth orbiting KOI-351, a yellow-white F-type star 2.77 thousand light-years from Earth. It is about 1.3 times the size of Earth. It completes an orbit every 14.4 days at 0.12 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 709 K (436 °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 2017 by transit with Kepler. A planet crosses its star and dims it by a tiny, periodic fraction. KOI-351 has 8 known planets; the others are KOI-351 b, KOI-351 c, KOI-351 d, KOI-351 e, KOI-351 f, KOI-351 g and KOI-351 h.
