About this world
Kepler-988 b is a sub-Neptune orbiting Kepler-988, an orange dwarf 994 light-years from Earth. It is about 2.1 times the size of Earth. It completes an orbit every 17.8 days at 0.11 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 368 K (95 °C): too cold 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 Kepler. A planet crosses its star and dims it by a tiny, periodic fraction.
