A team of NASA scientists discovered another Earth-sized exoplanet orbiting in its star’s habitable zone that could potentially retain liquid water, the U.S. space agency announced on Tuesday.
The planet—called “TOI 700 e”—is about 95 percent of Earth’s size and likely rocky. It was spotted in a system in the southern hemisphere about 100 light-years away from Earth while orbiting a small, cool M dwarf star dubbed “TOI 700.”
In 2020, scientists discovered the system’s first Earth-sized planet called “TOI 700 d.” There are four known planets in total orbiting TOI 700, although only two—which are e and d—exist in the star’s habitable zone….
