Astronomers Find Five Rocky Planets Around a Small Red Dwarf, Including a Super-Earth in the Habitable Zone

Universe Today - Wed, 07/30/2025 - 7:37am

NASA's Transiting Exoplanet Survey Satellite (TESS) detected three rocky planets around the M-dwarf L 98-59 in 2019. While two are expected to be hot, rocky worlds, the third could be covered by a global ocean. A fourth planet was discovered in 2021, and now, additional study has revealed a fifth planet, a super-Earth in the star's habitable zone.
