About this world
TOI-6330 b is a gas giant orbiting TOI-6330, a cool red dwarf 453 light-years from Earth. It is about 0.97 times the size of Jupiter and holds 10 Jupiter masses. It completes an orbit every 6.85 days at 0.058 AU from its star, closer than Mercury is to the Sun, on a strongly elongated orbit (e = 0.34).
Its equilibrium temperature is about 495 K (222 °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 2025 by transit with Transiting Exoplanet Survey Satellite (TESS). A planet crosses its star and dims it by a tiny, periodic fraction.
