Gas giant Saturn influenced by a tiny moon
Enceladus is one of the moons of the planet Saturn. A study led by researchers at the Plasma Physics Laboratory (LPP*) reveals that the magnetic interaction between the two bodies extends over much greater distances than previously known—more than 500,000 kilometers. This finding was made possible by data from the Cassini mission.
