Summary:
- NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered a rare three-star system with three planets orbiting the central stars.
- This system, named TOI-451, is the first known system with three stars and three exoplanets, making it a unique and intriguing find for astronomers.
- The three planets in the system are all super-Earths, meaning they are larger than Earth but smaller than Neptune, and they orbit their stars very closely, completing their orbits in just a few days.
