Scientists have made a groundbreaking discovery: a giant planet, TOI-6894b, orbiting a tiny red dwarf star—something previously believed to be impossible.
TOI-6894b, a gas giant planet, roughly the size of Saturn, has been found orbiting an unusually small red dwarf star.
This rare pairing defies current models, which say small stars don’t have enough material in their surrounding disks to form such large planets.
The planet was found about 241 light-years from Earth in the constellation Leo.
TOI-6894b is about 1.07 times the diameter of Saturn but has just over half its mass.
This makes the planet very low in density, similar to that of a beach ball. Despite its large size, the planet orbits extremely close to its host star, completing a full revolution in just under three Earth days.
The star it orbits, TOI-6894, is a red dwarf with only about 21% the mass of the Sun and roughly 250 times dimmer.
In terms of physical size, the star is just 2.5 times wider than the planet itself, a remarkable size ratio rarely seen in planetary systems.
