Veenus on P\u00e4ikesest teine planeet, mist\u00f5ttu asub ta taevas alati P\u00e4ikesele \u00fcsna l\u00e4hedal. Ta paistab silmapaistva hommiku- v\u00f5i \u00f5htut\u00e4hena \u2013 \u00f6\u00f6taevas on ta Kuu j\u00e4rel k\u00f5ige heledam objekt. Teleskoobi abil on n\u00e4ha, kuidas ta l\u00e4bib faase, t\u00e4pselt nagu Kuu.<\/p>\n<\/div>\n

Veenus on nii ere, sest seda katavad pilved, mis peegeldavad suure osa sissetulevast p\u00e4ikesevalgusest. Kollakad pilved koosnevad v\u00e4\u00e4vlist ja v\u00e4\u00e4velhappest.<\/p>\n

M\u00f5nes m\u00f5ttes on Veenus Maa kaksik. See on umbes sama suur ja koosneb samadest kivimaterjalidest. Samuti asub see meist l\u00e4hemal kui \u00fckski teine planeet. Siiski on see kaetud paksu s\u00fcsinikdioksiidist koosneva atmosf\u00e4\u00e4riga \u2013 gaasiga, mida me v\u00e4lja hingame. See atmosf\u00e4\u00e4r on nii tihe, et selle l\u00e4bimine oleks nagu vees kahlamine.<\/p>\n

S\u00fcsinikdioksiid hoiab kinni suurema osa P\u00e4ikesest p\u00e4rit soojusest. Ka pilvekiht toimib nagu tekk. Selle tulemuseks on \u201ckontrollimatu kasvuhooneefekt\u201d, mis on p\u00f5hjustanud planeedi temperatuuri t\u00f5usu 465 \u00b0C-ni \u2013 see on piisavalt kuum, et sulatada pliid. See t\u00e4hendab, et Veenus on isegi kuumem kui Merkuur.<\/p>\n

Ilma erikaitseta sureks Veenuse k\u00fclastaja koheselt \u2013 tohutu \u00f5hur\u00f5hu all purustatuna, atmosf\u00e4\u00e4ris l\u00e4mbumisest, k\u00f5rvetavast kuumusest t\u00e4iesti k\u00f5rbenuna ja happe poolt lahustatuna.<\/p>\n

Veenuse pinda on kaardistatud radari abil. Kaartidel on n\u00e4ha tuhandeid vulkaane ja kokkup\u00f5rkekraatreid. Seal on kaks peamist m\u00e4giala, millest \u00fche m\u00e4estik on k\u00f5rgem kui Mount Everest.<\/p>\n

Veenust on k\u00fclastanud k\u00fcmneid kosmoses\u00f5idukeid, kuid paljud saladused on endiselt lahendamata. ESA kosmoses\u00f5iduk \u201eVenus Express\u201c on alates oma saabumisest 2006. aasta aprillis tiirlenud planeedi \u00fcmber peaaegu polaarsel orbiidil. Enamik selle pardal olevatest seadmetest on uurinud tihedat atmosf\u00e4\u00e4ri ja kiiresti liikuvat pilvkatet v\u00f5i seda, kuidas P\u00e4ike planeeti m\u00f5jutab. Samas on selle infrapunaandur suutnud kaardistada osa planeedi pinnast ja n\u00e4idata, et Maa naaberplaneedil v\u00f5ivad eksisteerida aktiivsed vulkaanid.<\/p>","protected":false},"excerpt":{"rendered":"
