Defying Planet Formation Theories: A Giant Planet Around a Tiny Red Dwarf

Astronomers have discovered a giant planet, TOI-6894b, orbiting the small red dwarf star TOI-6894, which is only about 20% the mass of our Sun. This discovery challenges leading planet formation theories, as core accretion models predict that giant planets are unlikely to form around such low-mass stars. TOI-6894b's low density and cool temperature make it a unique case, offering an excellent opportunity to study planetary atmospheres. Future observations by the James Webb Space Telescope will investigate TOI-6894b's atmosphere to unravel the mysteries of its formation.
