Summary:
- Astronomers have discovered a massive exoplanet orbiting a small, cool star, which challenges current theories of planet formation.
- The planet, called TOI-5205b, is about 5 times the mass of Jupiter but orbits its host star in just 2.8 days, much closer than expected for a planet of its size.
- This discovery suggests that our understanding of how planets form and evolve around low-mass stars is incomplete, and it could lead to new insights into the diversity of planetary systems.
