Obstoj naravnega satelita v Enckejevi vrzeli so napovedali že leta 1985 [[Jeffrey N. Cuzzi]] in [[Jeffrey D. Scargle]] <ref>Cuzzi, J. N.; and Scargle, J. D.; [http://adsabs.harvard.edu//full/seri/ApJ../0292//0000276.000.html ''Wavy Edges Suggest Moonlet in Encke's Gap''], Astrophysical Journal, Vol. 292 ([[1. maj]], [[1985]]), pp. 276–290</ref>, ko je sonda Voyager letela mimo Saturna. Na posnetkih so opazili valovite motnje v sistemu obročev. Že takrat so Mark R. Showalter in drugi astronomi zračunali kakšno bi lahko bilo telo (velikost in tirnico), ki te motnje povzroča. Pozneje so na posnetkih Voyagerja 2 našli luno na mestu, ki se je samo za 1 º razlikovalo od napovedane.
