TOI-3288 b: A Jupiter-Like World Around a Cool Red Dwarf

TOI-3288 is an M0±0.5 star located 654 light-years away. This small, cool red dwarf has a reported mass of 0.643 solar masses and a radius of 0.672 solar radii. Its temperature is 4070 K, cooler than the Sun's. All of these measurements describe the host star alone. One planet is known to orbit this star.

That planet, TOI-3288 b, is a Jupiter-like world discovered by the transit method in 2025. It has a mass of 536 Earth masses, roughly 1.69 times Jupiter's mass, and a radius of 12.2 Earth radii, larger than Earth's. Its mean density is 1.61 g/cm³, 0.292 times Earth's. The planet completes each orbit in just 1.43 days.
