Poyasnenie: Protei - vtoroi po velichine sputnik Neptuna, sleduyushii za tainstvennym Tritonom. Protei byl otkryt tol'ko v 1982 godu kosmicheskim apparatom Voyadzher-2. Eto dostatochno stranno, t.k. Neptun imeet men'shii sputnik - Nereidu - kotoryi byl otkryt 33 godami ran'she. Prichina, pochemu Protei ne byl otkryt ranee, zaklyuchaetsya v tom, chto ego poverhnost' ochen' temnaya, a ego orbita raspolozhena blizhe k Neptunu. Po forme Protei pohozh na korobku s nechetnym kolichestvom storon. Esli by on byl nemnogo massivnee, ego sobstvennaya gravitaciya pridala by emu sfericheskuyu formu.
