TOI-6894b : Giant Planet

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.
