Magnetic Fields Shape Moon Systems | Science News

Why does Jupiter have a whole fleet of giant moons while Saturn’s moon family is more modest? New research reveals it might come down to magnetic fields—Jupiter’s early, super-strong field created a protective bubble in its moon-forming disk, letting multiple large moons survive. Saturn’s weaker field couldn’t carve out such a safe zone, so its moons didn’t stick around the same way. Computer simulations back this up, suggesting magnetic strength could be the key to how many moons a planet ends up with—and even how moon systems form around exoplanets.
