About this world
TOI-6383 A b is a gas giant orbiting TOI-6383 A, a cool red dwarf (type M3) 559 light-years from Earth. It is about 1 times the size of Jupiter and holds 1 Jupiter masses. It completes an orbit every 1.79 days at 0.023 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 745 K (472 °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 2024 by transit with Transiting Exoplanet Survey Satellite (TESS). A planet crosses its star and dims it by a tiny, periodic fraction.
