The boholo le ka boima ya Sun

Letsatsi oa iphuthumatsa 'me illuminates lefatšeng. Phelang ho lona ka be ho bile khonehe ntle matla la leseli. Ena e sebetsa ho motho eo le ho eohle ea limela tsa lefatše, liphoofolo. Letsatsi ka mafolofolo le thulaganyo tsohle li etsahala Lefatšeng. Lefatše a fumana ho tswa ho a letsatsi ha feela khanya le mocheso. Ka bophelo ba polanete ea rōna e phallang ea likaroloana tswelela pele susumetsoa ke mefuta e fapaneng ya mefuta e meng ea mahlaseli a kotsi a letsatsi.

Sun - naleli e haufi-ufi ho rona. Letsatsi lithuto tsa fana ka tlhahisoleseding e mabapi le maemo a a itšoare ka tse etsahalang ka hare-hare tsa eona le ka holim'a metsi, lumella hore re utloisise sebōpeho 'meleng ea' mele stellar, e re sheba ka dimensionless ntlha halimang. Ho ithuta dithulaganyo ka etsahalang haufi le holim 'a letsatsi, o thusa ho utloisisa tšobotsi liketsahalo tsa sepakapakeng haufi-Lefatšeng.

Letsatsi - bohareng ba setsi sa rōna sa lipolanete, eo e boetse e akarelletsa lipolanete 8, e mengata e satellitari lipolanete, batho ba likete ba asteroids, meteoroids, comets, interplanetary khase, lerōle. Tsamaisong ea letsatsi boima Letsatsi e nang le 99,866% ea boima ba 'mele palo yohle. Ka mantsoe a bolepi ba linaleli le hole ho tswa ho Sun ho Earth e nyenyane: leseli ke metsotso 8 feela.

boholo letsatsi a hloka tlhokomelo e khethehileng. Sena ke e khōlō, eseng feela ka ka boholo, empa hape ka ho ya ka naleli eo. bophara ba sona e leta bophara ea Lefatše ke makhetlo a 109 le bophahamo ba modumo, le eena, -. Ho makhetlo a limilione tse 1.3.

Lekantsoeng holim mocheso oa Letsatsi - likhato 5800, kahoo hoo e batlang e le khanyetsa khanya tšoeu, empa ka lebaka la ho absorption matla le hasanya ea lekgutshwanyane sebakeng tsa lefatše sepakapaka ho toba letsatsi manyenyane khanya haufi le holim 'a lefatše fumana mosehla.

'Misa oa Letsatsi - 1.989 * 10 ^ 30 lik'hilograma. palo ena e khōlō ho feta boima ea Lefatše ka 333 tse sekete. Times. The segokanyipalo sa karolelano ea ntho e lekanang le 1.4 g, / cm3. Ka karolelano segokanyipalo ea Lefatše ka holimo hoo e ka bang 4-lesaka. Ho phaella moo, ho na le khopolo e thutong ea linaleli le boima ba letsatsi - yuniti ya tekanyo ea boima ba 'mele, e leng e sebelisoa ho hlahisa le boima ba linaleli le lintho tse ling tsa thuto ea linaleli (lihlopha tsa linaleli tse).

The gaseous boima a letsatsi e tshwerweng ke khahloa ke ho tloaelehile hore ho bohareng. The le dikarolo e ka holimo ea boima ba 'mele ea bona e a petetswa tebileng,' me le eketseha botebo ba lera khatello ea e eketseha.
