Enceladus is just 504 kilometres across — roughly half the length of Great Britain — yet a 2026 study traced its electromagnetic Alfvén-wave wake at least 504,000 kilometres downstream through Saturn’s magnetosphere, farther than the Moon ever travels fro - spacedaily.com

Cassini data reveal that tiny Enceladus drives a main and reflected Alfvén-wave system through Saturn’s magnetosphere for at least half a million kilometres.
