TOI-2109 b is a scorching hot exoplanet that orbits its star, TOI-2109, at a dizzying pace, discovered in 2021 by the Transiting Exoplanet Survey Satellite (TESS). This fiery world is a true speedster, zipping around its star so quickly that a year on TOI-2109 b is incredibly short by Earth standards. Thanks to TESS’s keen eye and its high-tech CCD array, we spotted this glowing inferno as it passed in front of its star, dipping the starlight just enough to catch our attention. Imagine a planet so close to its sun that it blazes with extreme heat and fierce stellar winds—a real cosmic sauna! TOI-2109 b is a sizzling jewel in the vast gallery of alien worlds, reminding us how wildly diverse planets can be.
