A hot and rocky exoplanet known as a super-Earth has been discovered orbiting one of the oldest stars in our Milky Way galaxy, according to a new study. The exoplanet, called that because it’s located outside our solar system, is about 50% larger than Earth and has three times the mass — which makes it a super-Earth by astronomy standards. Even so, the planet, known as TOI-561b, only takes less than half an Earth day to complete one orbit around its host star. “For every day you’re on Earth, this planet orbits its star twice,” said Stephen Kane, study coauthor and astrophysicist at the University of California, Riverside, in a statement.
