TESS Spots Saturn-like Planet Orbiting M-dwarf Star

NASA's TESS has discovered a new exoplanet, TOI-5344 b, orbiting an M-dwarf star. The planet is similar in size and mass to Saturn and is nearly 10 times larger and 135 times more massive than Earth. It joins a small group of giant exoplanets around M-dwarf stars and has a density of 0.8 g/cm3. The parent star, TOI-5344, is estimated to be 7.1 billion years old and has a high metallicity. Astronomers hope that further discoveries of similar exoplanets will shed light on the formation and evolution of giant exoplanets.
