Ukubuyela kweyethu Uhlelo lomkhathi, sithola amaplanethi ayisishiyagalombili aneziphuphutheki zawo kanye nenkanyezi yethu iLanga. Namuhla siza ukukhuluma ngeplanethi encane kunazo zonke ezungeza iLanga. Iplanethi iMercury. Ngaphezu kwalokho, yiyona eseduzane kunazo zonke. Igama layo livela esithunywa sabonkulunkulu futhi akucaci ukuthi sitholwe nini. Ingenye yamaplanethi amahlanu angabonakala kahle eMhlabeni. Ngokuphikisana ne- iplanethi iJupiter incane kunazo zonke.
Uma ufuna ukwazi ngokujule ngale planethi, kulokhu okuthunyelwe sizokutshela konke ongakwenza
Iplanethi iMercury
Ezikhathini zakudala kwakucatshangwa ukuthi iplanethi iMercury yayihlala ibhekene neLanga. Ngendlela efanayo neNyanga noMhlaba, isikhathi sayo sokujikeleza sasifana nesikhathi sokuhumusha. Kuthatha kuphela izinsuku ezingama-88 ukuzungeza ilanga. Kodwa-ke, ngo-1965 izinkanuko zathunyelwa ku-radar okwakungenziwa ngayo ukuthi isikhathi sayo sokujikeleza siyizinsuku ezingama-58. Lokhu kwenza izingxenye ezimbili kwezintathu zesikhathi sakhe ukuhumusha. Lesi simo sibizwa ngokuthi i-orbital resonance.
Ukuba yiplanethi ene-orbit encane kakhulu kunaleyo yoMhlaba, kuyenza isondele kakhulu kwiLanga. Ithole isigaba seplanethi encane kunazo zonke kweziyisishiyagalombili kusistimu yelanga. Phambilini, uPluto wayemncane kunabo bonke, kepha ngemuva kokukuthatha njenge-planetoid, iMercury iyona engena esikhundleni.
Ngaphandle kobukhulu bayo obuncane, Kungabonakala ngaphandle kwesibonakude esivela eMhlabeni sibonga ukusondela kwaso kwiLanga. Kunzima ukubona ngokukhanya kwayo, kepha kungabonakala kahle kusihlwa ngokushona kwelanga entshonalanga futhi kungabonakala kalula emkhathizwe.
Izici eziyinhloko
Kungenxa yeqembu lamaplanethi angaphakathi. Yakhiwe ngezinto eziguqukayo nezinamatshe, inhlanganisela yangaphakathi ehlukahlukene. Ubukhulu bamakhemikhali bufana kakhulu. Inesici esifanelekile njengeplanethi iVenus. Futhi kuyiplanethi engenaso isiphuphutheki semvelo esizungeza emzileni waso.
Ubuso bayo bonke benziwe ngedwala eliqinile. Ngakho-ke, ihlangene noMhlaba iyingxenye yamaplanethi amane aqine kakhulu kuhlelo lwelanga. Ngokusho kososayensi, le planethi ibilokhu ingenamsebenzi ezigidini zeminyaka. Ubuso bayo bufana nobenyanga. Ifaka ama-craters amaningi akhiwe ngokushayisana kwama-meteorites nezinkanyezi ezinomsila.
Ngakolunye uhlangothi, inezindawo ezibushelelezi nezimthende ezinesakhiwo esifana nesamawa. Ziyakwazi ukwelula amakhulu namakhulu amamayela futhi zifinyelele ekuphakameni kwemayela. Umnyombo wale planethi Iyinsimbi futhi inobubanzi obungamakhilomitha acishe abe ngu-2.000 XNUMX. Olunye ucwaningo luqinisekisa ukuthi isikhungo salo sakhiwe ngensimbi eyakhiwe njengaleyo yeplanethi yethu.
Tamaño
Ngokuqondene nosayizi weMercury, inkudlwana kuneNyanga. Ukuhumusha kwayo kushesha kakhulu kusistimu yonke yelanga ngenxa yokusondela kwayo kwiLanga.
Ebusweni bayo kunezakhiwo ezithile ezinemiphetho ezivela ezindaweni ezahlukahlukene zokulondolozwa. Amanye ama-craters mancane kanti imiphetho emangelengele ivezwa kakhulu umthelela wama-meteorites. Inezindishi ezinkulu ezinamasongo amaningana nenombolo enkulu yemifula ye-lava.
Phakathi kwawo wonke ama-craters kukhona eyodwa egqame ngayo usayizi obizwa ngeCarlori Basins. Ububanzi bayo bungamakhilomitha ayi-1.300. I-crater yalobukhulu bekufanele idale ama-projectiles afinyelela kumakhilomitha ayi-100. Ngenxa yemithelela eqinile futhi eqhubekayo yama-meteorite nezinkanyezi ezinomsila, izindandatho zezintaba eziphakemeyo ezingafika kumakhilomitha amathathu sezakhiwe. Ukuba yiplanethi encane kangako, ukushayisana kwama-meteorite kudale amagagasi okuzamazama komhlaba aye kolunye uhlangothi lomhlaba, enza indawo yomhlaba edideke ngokuphelele. Lapho lokhu sekwenzekile, umthelela wadala imifula yodaka.
Inamawa amakhulu akhiqizwa ukupholisa nangokuncipha ngosayizi wamakhilomitha amaningi. Ngalesi sizathu, kwakhiwa uqweqwe olunemibimbi olwakhiwe ngamawa amakhilomitha amaningana ukuphakama nokude. Ingxenye enhle yobuso bale planethi imbozwe amathafa. Lokhu kubizwa ososayensi indawo ye-intercrater. Kumele ukuthi zakhiwa lapho izindawo zasendulo zazingcwatshwa yimifula yodaka.
Ukushisa
Ngokuqondene nokushisa, kucatshangwa ukuthi ukusondelana neLanga kufudumele kakhulu kunakho konke. Noma kunjalo, akunjalo. Izinga lokushisa layo lingafinyelela kuma-degree angama-400 ezindaweni ezishisa kakhulu. Ngokuzungeza ngokunensa ngokwako, kubangela ukuthi izifunda eziningi zeplanethi zivikelwe kude nemisebe yeLanga.Kulezi zindawo ezibandayo, amazinga okushisa angaphansi kuka -100 degrees.
Amazinga okushisa abo ahlukahlukene kakhulu, angaya phakathi kuka -183 degrees Celsius ebusuku no-467 degrees Celsius ngosuku, lokhu kwenza iMercury ibe ngelinye lamaplanethi ashisa kakhulu kuSolar System.
Izintshisakalo zeplanethi iMercury
- IMercury ithathwa njengeplanethi enemigodi eminingi kakhulu eSolar System. Lokhu bekungenxa yokuhlangana okungenakubalwa nokukhubeka ngezinkanyezi ezinomsila ezingenakubalwa kanye nama-asteroid futhi lokho kube nomthelela ebusweni bayo. Iningi lalemicimbi yokwakheka komhlaba ibizwa ngamagama abaculi abadumile nababhali abaziwayo.
- Intaba enkulu kunazo zonke iMercury enayo ibizwa ngeCaloris Planitia, le crater ingalinganisa cishe amakhilomitha ayi-1.400 ububanzi.
- Ezinye izindawo ebusweni beMercury zingabonakala ngokubukeka okushwabene, lokhu kungenxa yokuncipha okwenziwe yiplanethi lapho ingqamu ipholile. Umphumela wokuncipha kweplanethi njengoba umongo wayo upholile.
- Ukuze ukwazi ukubona iMercury evela eMhlabeni, kufanele kube sekuhwalala, okungukuthi, ngaphambi kokuphuma kwelanga noma ngemuva nje kokushona kwelanga.
- EMercury ungabona ukuphuma kwelanga okubili: Oqaphelayo ezindaweni ezithile ubengabona lesi simanga esihle lapho iLanga livela khona emkhathizwe, ame, abuye futhi lapho ebelishiye khona, abuye aphume esibhakabhakeni aqhubeke nohambo.
Ngalolu lwazi ungafunda kabanzi ngale planethi enhle.
