‘Super-Earth’ discovered orbiting one of the galaxy’s oldest stars

The video discusses the planet TOI-561B, located in the Galactic thick disk of the Milky Way, 280 light years away. TOI-561B is 50% larger than Earth and three times its mass, orbiting its star twice every Earth day. Its surface temperature is extremely high, making it uninhabitable. The planet's region has fewer heavy elements, contributing to its Earth-like density. The system also contains two larger, less dense planets. TOI-561B was observed using the WM Keck Observatory, and findings are published in the Astronomical Journal.
