Ku dhowaad 99% of mass guud ee nidaamka loo baahan yahay xiddiga this. Oo kaliya 1% inta kale ee dunida iyo walxaha yimid. Xaaladdan oo kale, soo haray 99% ka mid ah ay mass - waa meerayaasha Rafaa.

By ka dhisan nidaamka ka mid ah Jupiter, Saturn, Uranus, Neptune. Jupiter - meeraha ugu weyn. Its mass ku saabsan tahay 318 jeer ka mass of Earth. Oo haddii aad isugu kuwii kale oo dhan ee caalamka, ay mass ka badan mass ee caalamka waa 2.5 jeer. Waxaa lagu gartaa laba qaybood oo waaweyn: hydrogen iyo helium. Jupiter caan ku tahay tiro badan oo ah satalayt. Waxay lahaa 65 Oo ugu weyn, Ganymede, intee ka badan ee Mercury caalamka. Sidoo kale, ee Satellite ee Jupiter la mid ah in la eego qaar ka mid ah in ay ku meerayaasha tan kuwa dhulkuna waa.

Saturn waa nidaamka giraanta garan karo. Waxaa kaalinta labaad ee group-ka, "ayuu meerayaasha Rafaa." At 95 jeer mass of Earth. On Halabuurka ee caalamka ugu eg Jupiter, laakiin waxa uu leeyahay cufnaanta aad u yar, taas oo la mid ah mugga biyaha. Saturn uu leeyahay 62 satalayt. Titan - moon kaliya ee Nidaamka Solar in uu leeyahay jawi wax ku ool ah.

meeraha saddexaad ee ugu weyn - Uranus, ka meerayaasha dibadda u fudud yahay. ay mass waa 14 jeer ka weyn yahay dhulka. Waxaa xusid mudan in Uranus isku bedbedeli doono agagaarka The Sun "on your kooxda". Waxa uu u muuqday in uu kusii in ay falagiisuu. Shanqarta tiro badan oo kulaylka meel, inkastoo xaqiiqda ah in ubucda ah oo qabow badan kooxda kale ee gaaska. Waxay leedahay 27 satalayt.

The mass labaad ee ugu weyn, laakiin ma aha, meeraha - Neptune. miisaanka Neptune ahaa 17 tacsida Earth. Waa dheeraad ah oo cufan, laakiin ma dhaadheer kulayl aad u badan meel sida, tusaale ahaan, Saturn ama Jupiter. Neptune 13 satalayt (oo loo yaqaan in ay sayniska). ugu weyn - Triton. waxaa On waa geysers of nitrogen dareere ah. Triton guuro dhinaca ka soo horjeeda oo waxaa ku weheliyay astiriyoodhada.

The meerayaasha Rafaa leeyihiin dhegyadii iyaga u gaar ah. Inta lagu jiro ay kacaanka hareeraha dhidibka ma aha in ka badan siddeed iyo toban saacadood. Oo iyana waxay u di'in shaandheyn - layers. Ugu dhaqsaha badan qoqobada suunka Equatorial. xaalad Tan waxa u sabab xaqiiqada ah in meerayaasha kuwanu ma adag, oo uluhu waa la Tifaftirayaasha badan denser. Saturn iyo Jupiter Aasaaska - helium iyo hydrogen, iyo Uranus Neptune ku jira ammonia, biyaha iyo methane.
