About this world
TOI-2981 b is a gas giant orbiting TOI-2981, a yellow, Sun-like star 1.72 thousand light-years from Earth. It is about 1.2 times the size of Jupiter and holds 2 Jupiter masses. It completes an orbit every 3.6 days at 0.048 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 1,358 K (1,085 °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.
