Kukura kwepuraneti uye zvimwe zvinhu zvezuva

Pasi pezuva masere makuru makuru ekudenga - mapuraneti anofamba. Mukuwedzera kune Pasi mumasikati, kune mapuraneti akadai saMercury - ari pedyo nekuvhenekera, Venus - pasi repiri kubva kuSuva, Mars, Saturn, Jupiter, Neptune, Uranus. Iyi ndiyo urongwa hwemapuraneti. Pakutanga, Pluto airehwawo kune mapuraneti, asi kubva muna 2006 chinhu ichi chakasara chakasakara, uye nhasi chinorongwa se planetoids, mapuraneti maduku. Zvinenge zvose zvese zvinhu zvinogona kuonekwa mudenga nemaziso asina kuonekwa, Uranus chete uye Neptune chete anogona kuonekwa kuburikidza netescope.

Kuyera kwepurogiramu uye Sun  

Vanhu vakaziva nezve mapuraneti kubvira kare kare. Vavakidzani vepedyo vePasi ndivo Mars naVenus, vane radius makiromita 6052, nechekupedzisira Uranus uye Neptune.

Zvose zvisikwa zvokudenga zvezuva rinoparadzaniswa kuita zvikamu zviviri. Ikutanga inosanganisira zvinhu zveboka repasi, kana izvo zvinonzi mapuraneti emukati pedo neZuva - iri pasi, Mars, Mercury uye Venus. Zvose izvi zvisikwa zvekudenga zvine nzvimbo yakasimba, dzine unhu hwakakwirira, pasinei nechomukati chemvura. Iko huru pane iri boka iri Pasi.

Chikamu chechipiri chinosanganisira zvimwe zvinhu zvose, zvinonzi "giant mapuraneti." Iyo iri kure necheSain, uye kuenzana kwemapuraneti eboka iri kune yakakura kudarika nyika. Vanonziwo mapuraneti ekunze. Somuenzaniso, kuyerwa kweJupiter kune mazana matatu zvakapfuura kukura kwePasi. Mukuwedzera, mapuraneti makuru acho akasiyana mune zvaakagadzirirwa kubva kune zvisikwa zveboka repasi: izvo chaizvoizvo zvinosanganisira magasi (hydrogen ne helium), uye zvakafanana nedzimwe nyeredzi. Vanonziwo "gasi giants".

Izvo zviyero zvepurogiramu zvinokanganisa kukurumidza kwekuzungurudza zvakakomberedza mheyo yavo, nguva yezuva neusiku.

Mukuwedzera kune miviri yekudenga yakatsanangurwa, hurongwa hwedu hunosanganisira ma satellite emapuraneti. Pamwe chete, makumi matanhatu maserecheti anotenderera kumativi ose mapuraneti. Mwedzi ishamwari yePasi, Mars uye Neptune ine ma satelliti maviri ega ega. Mazhinji ma satellites muna Saturn ane gumi nemanomwe, uye mamwe awo akare kupfuura Mwedzi. Masheta mazhinji kubva kuUranus naJupiter, uye neMercury chete naVenus vakaramba vari voga.

Zviuru zvezvitunha zvakasiyana-siyana zvinotenderera mberi uye zvichiyambuka Solar System: comets, asteroids, mamiriyoni eemeteorites, zvinyorwa zveguruva guru guru nyaya, dzakapararira maatomu eakisiki akasiyana-siyana, nzizi dzeatomic particles.

Bhanhire re asteroid riri pakati peJupiter uye Mars. Iyo asteroid inhengo yemazuva ose. Izvo zviyero zve asteroids zvinosiyana kubva pamakumi emakumi emamita emamita kusvika zviuru zvemakiromita. Chikuru pane izvi ndiJuno, Pallas, Ceres.

Nenzira yakawanda, miviri yose yezvinhu zvakasvibirira yezuva yakarongeka nokuda kwekukwezva kwezuva. Vose vanopoteredza chiedza mune imwe ndege (maererano ne ecliptic), uye mune imwe nzira. Zvimwe chete ndezvimwe mavheti. Munenge mumiviri yose yekumatenga inotenderera ichikomba.

Ukuwanda kweSuva kunosvika 99.80% yehuwandu hwepasi rose. Masasa akasara 99% akatorwa nemafuta makuru (Saturn naJupiter). Maererano nevadzidzisi venyeredzi, ukama hwedu huri huri pasi pe 60.0 mabhiriyoni makiromita - zvakaoma zvikuru kufungidzira kure kure. Pakati peredzi kureba kunotaridzirwa mune zvidzidzo zvekudenga. Rimwe uye. Ie iyo yakaenzana nekuyera pakati peSuva neNyika (anenge 150.0 mami km).

Kuti ufungidzire zviyero zvezuva uye masikirwo emapuraneti, iwe unogona kushandisa muenzaniso unotevera, zviyero zvayo zvichaderedzwa nemabhiriyoni nguva. Nokudaro, kureba kwePasi iri 1.3 cm, mwedzi uchange uine masendimita makumi matatu kubva mairi, Jupiter ichave yakakura yemazambiringa, uye munhu anogona kuenzaniswa neatomu. Iyo yakareba yezuva ichava mamita imwe nehafu, uye ichave ine mamita 150 kubva pasi. Nyeredzi iri pedyo iri mumuenzaniso ichave iri kure nemakiromita zviuru makumi mana.
