CNN —Astronomers have discovered a “super-Earth,” or a world larger than our planet, orbiting a star about 137 light-years away. The super-Earth exoplanet, known as TOI-715b, orbits a red dwarf star that is cooler and smaller than our sun. “This discovery is exciting as it’s the first super-Earth from TESS to be found within the conservative habitable zone,” Dransfield said. If the Earth-size planet is confirmed, it will become the smallest planet yet that TESS has found in a habitable zone. TOI-715b’s star has only shown a couple of flares within the past two years and isn’t considered active, making it an old star, Dransfield said.
