Poyasnenie: Tefiya - odin iz samyh bol'shih i blizkih k planete sputnikov Saturna. Kosmicheskii apparat Kassini, nahodyashiisya seichas na orbite Saturna, proletel okolo zamerzshego sputnika v konce oktyabrya i peredal samye podrobnye izobrazheniya posle apparatov Voyadzher, kotorye priblizhalis' k Tefii v nachale 1980-h godov. Tefiya pochti polnost'yu sostoit iz vodyanogo l'da. Na nei est' ogromnyi udarnyi krater, zanimayushii pochti celoe polusharie (na etom snimke ne viden). To, chto udar, v rezul'tate kotorogo obrazovalsya etot krater, ne razrushil sputnik, mozhet sluzhit' svidetel'stvom, chto v proshlom Tefiya ne byla polnost'yu zamerzshei. Dva men'shih sputnika - Telesto i Kalipso, obrashayutsya vokrug Saturna vperedi i pozadi Tefii. Dzhovanni Kassini otkryl Tefiyu v 1684 godu. Blizkii prolet apparata Kassini okolo Tefii zaplanirovan na sentyabr' 2005 goda.
