About this world
TOI-2537 b is a gas giant orbiting TOI-2537, an orange dwarf 603 light-years from Earth. It is about 1 times the size of Jupiter and holds 1.3 Jupiter masses. It completes an orbit every 94.1 days at 0.37 AU from its star, closer than Mercury is to the Sun, on a strongly elongated orbit (e = 0.36).
Its equilibrium temperature is about 338 K (65 °C): too cold 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. TOI-2537 has 2 known planets; the others are TOI-2537 c.
