Litekanyo tsa lipolanete le lintho tse ling tsamaiso e khopo a letsatsi

Ho susumelletsa ho pota letsatsi robeli mele kholo ka ho fetisisa ea leholimo - lipolanete. Ho feta moo Earth tsamaisong lipolanete letsatsi teng kang Mercury - haufi-ufi le mohloli oa leseli la, Venus - polanete ea bobeli e tsoang letsatsing, Mars, Saturn, Jupiter, Neptune, Uranus. Ena ke taelo ea lipolanete. Pele ngotsoe ke lipolanete le goober, empa ho tloha 2006 e le sebaka Sepheo lahlehileng boemo ba eona, 'me kajeno ho o bitsoa dihlopha tsa planetoids, lipolanete tse nyenyane. Hoo e ka bang lintho tsohle tse sepakapakeng se ka bonoa sepakapakeng le mahlo, empa Uranus le Neptune bona ka sebonela-hōle sa.

Litekanyo tsa lipolanete le Sun.  

About lipolanete tsebisoe batho ho tloha mehleng ea boholo-holo. Baahelani haufi ke Earth le Mars Venus, eo radius o lekana le km 6052, e hōle-hōle - uraniamo le Neptune.

tsohle lihloliloeng tsa leholimo ea tsamaiso ea letsatsi li arotsoe ka mekhahlelo e 'meli. Pele ke ntho e le tsa lefatše, kapa seo ho thoeng ke lipolanete ka hare e haufi-ufi ho Sun - ke Earth, Mars, Mercury le Venus. Kaofela ha 'mele tsena oa leholimo holim'a ka thata, ba ile ba ba le segokanyipalo phahameng, ho sa tsotellehe ea mantlha ea kelello e mokelikeli. Kholo ka ho fetisisa sehlopheng sena ke Lefatšeng.

Mokhahlelo oa bobeli ho akarelletsa ho lintho tse ling tsohle, e tsejoang e le "lipolanete seqhenqha." Ba leng teng furthest tswa Sun, lipolanete le boholo ba sehlopha sena ke haholo phahametse lefatše. Leha ho le joalo ba ba bitsoa lipolanete tsa ka ntle. Mohlala, boima ba 'mele Jupiter ka makhetlo a makholo a mararo le boholo ba Earth boima. Ho phaella moo, lipolanete seqhenqha fapana ka sebopeho ho tswa beha dintho tsa lefatše: di haholo-holo a qapa ea likhase (hydrogen le helium), 'me tsena tse tšoanang le linaleli tse ling. Ba ne ba boetse ba bitsoa "linatla khase".

Boholo bo ea lipolanete ama ajoa lebelo bona pota selekane tsa lona, bolelele ba bosiu le motšehare.

Ntle ho moo lihloliloeng tsena tsa leholimo ka sebopeho ea tsamaiso ya rona e na le lipolanete satellitari. lipolanete tsohle ho bapaloa pota satellitari 54. Khoeli ke motsoalle oa Earth e, Mars le Neptune na tse peli tse li-satellite. Boholo ba satellitari tsa Saturn - lesomesupa, 'me ba bang ba bona ba le boholo kholoanyane ho feta Moon. satellitari tse ngata tsa Uranus le Jupiter, 'me feela Mercury le Venus ba setse a le mong.

tsamaiso e khopo a letsatsi e mong leeto ka bolelele le bophara ba le 'mele tse sekete fapaneng tse nyenyane: comets, asteroids, meteorites limilione likaroloana tsa khase le lerōle tse bonahalang, ho liathomo hasane likarolo fapaneng lik'hemik'hale, melapo ea likaroloana tsa athomo.

The asteroid lebanta teng pakeng tsa Jupiter le Mars. Asteroid - e nyenyane ea leholimo 'mele. Boholo bo ea lipolanete, asteroids Range ho tloha ka mashome a seng makae tsa limithara tse ho tse likete km. Kholo ka ho fetisisa ba bona ba Juno, Pallas, Ceres.

Ka kakaretso, le tsohle lihloliloeng tsa leholimo ea tsamaiso ea letsatsi ke ho equilibrium ka lebaka la ho khahloa-tsatsi. Kaofela ha bona ba ho bapaloa ka bophara leseling ka sefofane 'ngoe (ka ecliptic) le ka tsela e tsoanang. The ntle le mabaka feela tse ling comets. Hoo e ka bang 'mele kaofela oa leholimo ho bapaloa ka bophara a selekane lona.

Ka boima ba Letsatsi litlaleho tse ka bang 99,80% ea boima ba tsamaiso eohle letsatsi. Le boima ba setseng ho 99% ho kena linatla khase (Saturn le Jupitere). Ho ea ka litsebi tsa linaleli, boholo ba setsi sa rōna ke seng ka tlase ho limilione tse likete tse 60,0 km - ho hlahisang hole joalo ke ho le thata haholo. Pakeng tsa linaleli hole e lekanngoa ka diyuniti bolepi ba linaleli. hammoho le 'ngoe. e. ke sebaka se pakeng tsa letsatsi le lefatše (hoo e ka bang ba limilione tse 150,0. km).

Ho nahana ka boholo ba tsamaiso ea lipolanete a letsatsi le litekanyo, o ka sebelisa ea mohlala tse latelang, entsprechen seo ka sona a tla fokola ka makhetlo a limilione tse sekete. Kahoo, lefatše le bophara ba cm, 1.3, Moon tla teng le hōle ho tswa ho ba cm, 30, Jupiter tla boholo ba grapefruit le motho a ka bapisoa le athomo e. Letsatsi bophara e tla limithara tse 'ngoe le halofo,' me e teng limithara tse 150 ho tloha moo. Naleli e haufi e ea mohlala e tla fumaneha ka e leng sebaka sa km mashome a mane tse sekete.
