Tsamaiso ea letsatsi ke eng?
Context:Solar System[c] ke tsamaiso ea matla a khoheli ea letsatsi le lintho tse e potileng. E ile ea thehoa lilemong tse limilione tse likete tse 4,6 tse fetileng ka lebaka la ho putlama ha matla a khoheli a leru le leholohali la limolek'hule le pakeng tsa linaleli. Boholo bo boholo (99.86%) ba boima ba tsamaiso bo ka Letsatsi,'me boholo ba boima bo setseng bo teng polaneteng ea Jupiter. Tsamaiso ea lipolanete tse potolohileng Letsatsi e na le lipolanete tse robeli. Lipolanete tse 'nè tsa tsamaiso e ka hare - Mercury, Venus, Lefatše le Mars - ke lipolanete tsa lefatše, tse entsoeng haholo ka majoe le tšepe. Lipolanete tse' nè tse khōlō tsa tsamaiso e ka ntle li khōlō haholo ebile li boima ho feta tsa lefatše. Tse peli tse khōlō ka ho fetisisa, Jupiter le Saturn, ke linaleli tse khōlō tse nang le khase, tse entsoeng haholo ka haedrojene le helium; tse peli tse latelang, Uranus le Neptune, ke linaleli tse khōlō tse nang le leqhoa, tse entsoeng haholo ka lintho tse fofang tse nang le lintlha tse phahameng tsa ho qhibiliha ha li bapisoa le haedrojene le helium, tse kang metsi, ammonia le methane. Lipolanete tseo tse robeli li na le li-orbite tse batlang li le chitja tse haufi le sefofane sa potoloho ea Lefatše, se bitsoang ecliptic.  Ho na le palo e sa tsejoeng ea lipolanete tse nyane tsa li-dwarf le'mele e mengata e nyane ea Solar System e potolohang Letsatsi. [d] Tse tšeletseng tsa lipolanete tse kholo, lipolanete tse tšeletseng tse kholo ka ho fetisisa tse ka khonehang, le tse ngata tsa'mele e menyenyane li potolohile ka li-satellite tsa tlhaho, tseo hangata li bitsoang "likhoeli" ka mor'a Khoeli ea Lefatše. Likhoeli tse peli tsa tlhaho, khoeli ea Jupiter e leng Ganymede le khoeli ea Saturn e leng Titan, li kholo ho feta Mercury, e leng polanete e nyenyane ka ho fetisisa lefatšeng, le hoja e le e nyenyane,'me khoeli ea Jupiter e leng Callisto e batla e le khōlō. E 'ngoe le e 'ngoe ea lipolanete tse khōlō le tse ling tse nyenyane e pota-potiloe ke mehele ea lipolanete e entsoeng ka leqhoa, lerōle le khoeli e nyenyane. Lebanta la li - asteroid, le lipakeng tsa tsela eo Mars le Jupiter li tsamaeang ka eona, le na le lintho tse entsoeng ka majoe, tšepe le leqhoa. Ka nģ'ane ho potoloho ea Neptune ho na le lebanta la Kuiper le disk e hasaneng, tseo e leng lihlopha tsa lintho tse entsoeng haholo ka leqhoa le majoe.
Lentsoe solar le bolela "le amanang le Letsatsi", le nkiloeng lentsoeng la Selatine sol, le bolelang Letsatsi. Letsatsi ke lona le nang le matla a maholo a khoheli tsamaisong ea rōna ea lipolanete,'me tsamaiso ea lona ea lipolanete e lula e tsitsitse, e iphetola butle-butle ka ho latela li-orbite tse arohaneng tse pota-potileng letsatsi ka matla a khoheli
