Citizen scientists using NASA’s TESS mission have discovered TOI-4465 b, a rare, relatively cool gas giant about 400 light-years away.

Roughly six times Jupiter’s mass and 1.25 times its width, it orbits its star every 102 days in an elliptical path, with temperatures between 200 and 400 °F.

Unlike scorching “hot Jupiters” or frigid ice giants, TOI-4465 b occupies an underexplored middle ground, offering valuable clues about planetary system formation, Space.com has reported.

Its rarity makes it a prime target for future study with the James Webb Space Telescope.
