About this world
KOI-984 b is a Neptune-like planet orbiting KOI-984, a yellow, Sun-like star 824 light-years from Earth. It is about 4.3 times the size of Earth. It completes an orbit every 4.29 days at 0.05 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 1,022 K (749 °C): far too hot for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2022 by transit with Kepler. A planet crosses its star and dims it by a tiny, periodic fraction. KOI-984 has 2 known planets; the others are KOI-984 c.
