Novye sputniki Yupiter
 |
Yupiter XVII, XVIII, ...?
Okolo desyatka malen'kih nepravil'nyh sputnikov Yupitera byli otkryty nedavno. V eto zhe vremya bylo vyyavleno mnogo novyh lun Saturna i Urana.
Sputnik S/1999 J1 byl otkryt v hode proekta Nablyudatel' Kosmosa (Spacewatch) v Centre Malyh Planet v 2000 godu po snimkam sdelannym v 1999.
Nablyudeniya s VLT (Very Large Telescope) v iyule 2000 goda podtverdili sushestvovanie S/1999 J1 i utochnili ego razmery i parametry orbity.
S/2000 J11 dvizhetsya po orbite podobnoi orbitam Ledy, Gimalii, Lizitei i Elary (naklonenie orbity okolo 30 gradusov, dvizhenie po orbite - pryamoe).
Sredi novyh sputnikov tol'k S/2000 J1 obladaet podobnymi svoistvami.
Ostal'nye novye sputniki dvizhutsya po orbitam blizkim k orbitam Ananke, Karme, Pasifai i Sinope.
My obychno govorom, chto eti nepravil'nye sputniki - prosto "zahvachennye asteroidy". Odnako mehanizm ih zahvata neyasen. I esli govorit' pravdu, to my ne znaem kak oni popali tuda, gde ih obnaruzhili.
