Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our sun. Like many small stars, it is not expected to provide suitable conditions for the formation and hosting of a large planet.

Astronomers have been left puzzled by the discovery of an unusually large planet orbiting a remarkably small star, a cosmic pairing that defies existing theories of planetary formation.

Scientists have discovered a giant planet called TOI-6894b, orbiting a star that should be far too small to have formed it. The discovery could further challenge theories of planet formation.
