Proletev okolo
vneshnego kraya kolec Saturna, 16 yanvarya kosmicheskii apparat Kassini zapechatlel etot
vid Dafnisa
s samogo blizkogo rasstoyaniya.
Etot malen'kii sputnik, razmer kotorogo – okolo 8 kilometrov, obrashaetsya vnutri
sheli Kilera v sisteme yarkih kolec i
sozdaet volny.
Shirina etoi
vneshnei sheli – 42 kilometra, odnako
na snimke ona vyglyadit men'shei iz-za ugla zreniya Kassini.
Malen'kii sputnik peresekaet pole zreniya sleva napravo, ego slabaya gravitaciya
sozdaet volny v veshestve kolec na krayu sheli.
Slabyi sled iz veshestva kolec, pohozhii na volnu, tyanetsya za Dafnisom.
Vidny takzhe zamechatel'nye detali na Dafnise, vklyuchaya uzkii hrebet vdol' ekvatora,
veroyatno, sformirovannyi iz zahvachennyh chastic kol'ca.

Dafnis vytyanut, i on vrashaetsya. Prityazhenie veshestva kolec k nemu uvelichivaetsya, kogda vytyanutye chasti sputnika priblizheny k kol'cam. No vot chto ottalkivaet veshestvo kolec ot sputnika (veshestvo mezhdu grebnyami voln nahoditsya dal'she ot traektorii sputnika, chem veshestvo vperedi sputnika)?
