Yiplanethi enamatye eneatmosfera exineneyo kuzo zonke imizimba yamatye kwiSolar System, kwaye iyona kuphela enobunzima kunye nobukhulu obusondele kummelwane wayo ojikelezayo uMhlaba . Ukujikeleza ngaphantsi (ngaphakathi kwi-orbit yomhlaba), kubonakala kwisibhakabhaka soMhlaba esihlala sikufutshane neLanga, njengokuba "yinkwenkwezi yasekuseni" okanye "yinkwenkwezi yangokuhlwa". Ngelixa oku kukwayinyaniso kwiMercury, iVenus ibonakala ngokugqame ngakumbi, kuba iyeyesithathu into eqaqambileyo kwisibhakabhaka soMhlaba emva kweNyanga neLanga, ibonakala iqaqambile kunayo nayiphi na enye iplanethi yakudala efana neenkwenkwezi okanye nayiphi na into ezinzileyo . inkwenkwezi . Ngodumo olunjalo esibhakabhakeni soMhlaba, iVenus ngokwembali ibiyinto eqhelekileyo nebalulekileyo ebantwini, kuzo zombini iinkcubeko zabo kunye nenzululwazi ngeenkwenkwezi. IVenus inomazibuthe obuthathaka kunye nomoya oshinyeneyo wekharbhon dayoksayidi, nto leyo edala, kunye nelifu eligqumayo le-sulfuric acid, ifuthe eligqithisileyo legreenhouse . Oku kubangela umphezulu wobushushu obuphakathi kwe {{Convert|737|K|C F}} kunye noxinzelelo olutyumzayo lwamaxesha angama-92 oMhlaba kwinqanaba lolwandle, ukuguqula umoya ube lulwelo olugqithisileyo, ngelixa ukwindawo yokuphakama kwamafu engama {{Convert|50|km|mi}} . ngaphezulu komphezulu, uxinzelelo, ubushushu kunye nemitha yemitha ziyafana kakhulu kumphezulu woMhlaba. Iimeko ezinokuthi zilungele ubomi kwiVenus zichongiwe kumaleko ayo amafu, kunye nophando lwakutsha nje lufumene ubungqina, kodwa obungaqinisekanga, ubungqina bobomi kwiplanethi. IVenus isenokuba yayinamanzi angaphezulu kwamanzi kwasekuqaleni kwembali yayo, enokwenzeka ngokwaneleyo ukuba yenze iilwandlekazi, kodwa iziphumo ezibalekayo zegreenhouse ekugqibeleni ziye zaba ngumphunga nawaphi na amanzi, athi ke athatyathelwa esithubeni ngumoya welanga . Ngaphakathi, iVenus kucingelwa ukuba iqulathe undoqo ,&nbsp;ingubo, kwaye&nbsp;uqweqwe, oluya mva lukhupha ubushushu bangaphakathi ngentaba-mlilo esebenzayo, bubumba umphezulu ngokuphinda kuvele umphezulu omkhulu endaweni yepleyiti tectonics . IVenus yenye yeeplanethi ezimbini ezikwiSolar System ezingenazo iinyanga . IVenus inomjikelezo oye wacotha kwaye wajikela kwicala le-orbital direction ( retrograde ) ngemisinga enamandla kunye nokutsalwa kweatmosfera yayo. Oku kujikeleza kuvelisa, kunye nexesha leentsuku ezingama-224.7 zomhlaba kuthatha iVenus ukugqiba i-orbit ejikeleze iLanga (unyaka welanga waseVenusian), ubude belanga lelanga laseVenusian leentsuku ezili-117 zomhlaba, olona lude kwiSolar System, olukhokelela kwiVenusian. unyaka ungaphantsi kweentsuku ezimbini zeVenusian ubude. Iindlela zeVenus kunye noMhlaba zezona zikufutshane phakathi kwazo naziphi na iiplanethi zeSolar System, zisondela enye kwenye ngexesha le-synodic le-1.6 leminyaka. Ngelixa oku kubavumela ukuba basondele omnye komnye kwindawo engaphantsi kunezinye iiplanethi zeSolar System, iMercury ihlala ngokomndilili kufutshane nabo kunye nayo nayiphi na enye iplanethi, njengoko iMercury yeyona planethi isembindini kwaye idlula rhoqo. Oko kuthethiweyo, iVenus kunye noMhlaba phakathi kwazo unowona mahluko usezantsi kumandla womxhuzulane kunayo nayiphi na enye iperi yeplanethi yeSolar System. Ngo-1961, iVenus yaba yinto ekujoliswe kuyo kwinqwelomoya yokuqala phakathi kweeplanethi kwimbali yoluntu, ilandelwa zizinto ezininzi ezibalulekileyo zokuqala phakathi kweeplanethi njengokufika kokuqala okuthambileyo kwenye iplanethi ngo-1970. Ezi probe zenze kwacaca ukuba iziphumo ezigqithisileyo ze-greenhouse zidale iimeko ezicinezelayo, ingqiqo eye yazisa ngokubalulekileyo uqikelelo malunga nokufudumala kwehlabathi . <ref name="Dorminey 2018">{{Cite web|last=Dorminey|first=Bruce|date=2018-12-31|title=Galaxy May Be Littered With Dead Aliens Blindsided By Natural Climate Change|url=https://www.forbes.com/sites/brucedorminey/2018/12/31/galaxy-may-be-littered-with-dead-aliens-blindsided-by-natural-climate-change/|accessdate=2023-04-21|website=Forbes}}</ref> Oku kufunyanisiweyo kuye kwamisa uninzi lwengqwalasela kwiithiyori kunye nentsomi eyayisaziwa ngelo xesha malunga neVenus ngokuba yindawo ekunokuhlalwa kuyo okanye ehlala abantu.

I- Martian dichotomy ibonakala phezu komhlaba: ngokomyinge, umhlaba osemantla we-Mars uthambile kwaye ungaphantsi kune-hemisphere yayo esemazantsi. IMars ineatmosfera ebhityileyo eyenziwe ikakhulu yicarbon dioxide kunye neesathelayithi zendalo ezimbini ezimile ngendlela engaqhelekanga : Phobos kunye neDeimos . Ngokwejoloji, iMars isebenza ngokufanelekileyo, kunye needemoni zothuli ezityhutyha imbonakalo yomhlaba kunye neenyikima (i-analog yaseMartian ukuya [[Inyikima|kwiinyikima]] ) ezingcangcazela ngaphantsi komhlaba. Umphezulu we - Mars ubamba i -volcano enkulu yekhaka (i-Olympus Mons) kunye nenye yeenqanawa ezinkulu kwi-Solar System (Valles Marineris). Ukubaluleka kwe -orbital eccentricity ye-Mars kunye nokuthambeka kwe-axial kubangela utshintsho olukhulu lwamaxesha onyaka kugutyungelo lomkhenkce omhlophe kunye nokutshintsha kobushushu phakathi ukuya kuma- kumphezulu. Usuku lwe-Martian solar ( sol ) lulingana neeyure ezingama-24.5 kwaye unyaka welanga we-Martian ulingana neminyaka eyi-1.88 yoMhlaba. Njengezinye iiplanethi ezikwiSolar System, uMars wasekwa malunga neminyaka eyi-4.5 yeebhiliyoni eyadlulayo. Ngexesha likaNoah ukususela malunga ne-4.1 ukuya kwi-3.7 yeebhiliyoni zeminyaka eyadlulayo, umphezulu we-Mars wawuphawulwe ngeempembelelo zemeteor, ukwakheka kweentlambo, ukhukuliseko, kunye nobukho obunokubakho bamanzi [[Iilwandle|olwandle]] . Ixesha le-Hesperian ukusuka kwi-3.7 ukuya kwi-3.2-2 yeebhiliyoni zeminyaka eyadlulayo lalilawulwa yintaba -mlilo exhaphakileyo kunye nezikhukula eziqingqe imijelo emikhulu yokuphuma . Ixesha laseAmazon, elisaqhubeka ukuza kuthi ga ngoku, laphawulwa yimpembelelo yomoya kwiinkqubo zokwakheka komhlaba . Akwaziwa enoba ubomi bakha babakho kusini na kuMars . IMars iphakathi kwezona zinto ziqaqambileyo kwisibhakabhaka soMhlaba, kwaye ke yaziwa ukususela kumaxesha amandulo. Iimpawu zayo ze-albedo ezichasene kakhulu zenza ukuba ibe yinto eqhelekileyo yokujongwa ngeteleskopu . Ukusukela ekupheleni kwenkulungwane yama-20, uMars uye waphononongwa ziziphekepheke ezingaqhubiyo kunye neerovers, kunye ne-flyby yokuqala ye- ''Mariner 4'' probe ngo-1965, i-Mars orbiter yokuqala nge- ''Mars 2'' probe ngo-1971, kunye ne- ''Viking 1'' yokuqala ngo-1976.

Ifunyanwe ngorhatya lwe-23 kaSeptemba 1846 nguJohann Gottfried Galle, kunye neteleskopu yeBerlin Astronomical Observatory, kunye noHeinrich Louis d'Arrest, umfundi wenzululwazi ngeenkwenkwezi owamncedayo, INeptune yaba yiplanethi yokuqala ukufunyanwa ngayo. izibalo zemathematika kunokuphononongwa rhoqo: utshintsho olungaqhelekanga kwi-orbit ye-Uranus yabangela ukuba izazi ngeenkwenkwezi zikholelwe ukuba kukho, ngaphandle, iplanethi engaziwayo eyayiphazamisa ukujikeleza kwayo. Isijikelezi-langa sifunyenwe kwiqondo elinye nje lendawo eqikelelweyo. Inyanga iTriton yabhaqwa kamsinya emva koko, kodwa akukho nanye kwiisathelayithi zendalo ezilishumi elinesithathu zeNeptune eyafunyanwa phambi kwenkulungwane yama-20 . Isijikelezi-langa sikhe satyelelwa sisithukuthezi esinye kuphela, ''iVoyager 2'', eyadlula kufutshane naso ngo-Agasti 25, 1989.
