science πͺ Scientists find massive, rocky 'mega-Earth' exoplanet
Astronomers have discovered GJ 523b, a giant, dense exoplanet that challenges planet formation theories. This world is located in a system identified by TESS and is about 2.5 times wider than Earth. The planet packs roughly 23 times Earth's mass into its size, orbiting its star every 17.75 days. Its high density suggests it has little atmosphere despite its size, which is unexpected for such a massive body. Future research will aim to find more such planets to understand their formation path. πͺ
