About this world
TOI-3135 b is a gas giant orbiting TOI-3135, a yellow, Sun-like star 723 light-years from Earth. It is about 1.2 times the size of Jupiter and holds 1 Jupiter masses. It completes an orbit every 3.71 days at 0.048 AU from its star, closer than Mercury is to the Sun, on a strongly elongated orbit (e = 0.24).
Its equilibrium temperature is about 1,292 K (1,019 °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.
