About this world
Kepler-1984 b is a Neptune-like planet orbiting Kepler-1984, a cool red dwarf. It is about 0.61 times the size of Jupiter. It completes an orbit every 1.99 days at 0.024 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 675 K (402 °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 2023 by transit with Kepler. A planet crosses its star and dims it by a tiny, periodic fraction.
