Scientists found the world in data gathered by NASA's Transiting Exoplanet Survey Satellite (TESS). The planet orbits just one of the three stars, all of which are red dwarfs, and the system is about 22.5 light-years away from Earth. The newly-discovered world orbits LTT 1445A, the brightest member of the system. Named LTT 1445Ab, the planet is about 1.35 times bigger than Earth, about 8.4 times more massive, and is rocky in composition. It has an orbital period of 5.36 days and a surface temperature of about 311 degrees Fahrenheit (155 degrees Celsius).
