How Jupiter Cultivated More Large Moons than Saturn -- A magnetospheric cavity explains the difference

Jupiter and Saturn are both gas giant planets, yet their satellite systems are strikingly different. This contrast between their satellite systems may have arisen from differences in the strength of the planets’ magnetic fields during their formation. A research group including Prof. Masahiro Ogihara of the Tsung-Dao Lee Institute at Shanghai Jiao Tong University has proposed a new scenario to explain this difference through computer simulations. The results of this study were published online in Nature Astronomy on April 2, 2026.
