Neptuuni avastas 1846. aastal Berliini observatooriumi astronoom Johann Galle. Galle teadis, kust otsida, t\u00e4nu Prantsuse matemaatiku Urbain Le Verrier\u2019 arvutustele. Nii Le Verrier kui ka Inglismaal tegutsenud John Adams olid aru saanud, et n\u00e4htamatu planeet avaldas Uraanile t\u00f5mbej\u00f5udu, p\u00f5hjustades selle kiiruse aeglustumist v\u00f5i kiirenemist.<\/p>\n<\/div>\n

Neptuun osutus peaaegu Uraani identseks kaksikuks. See on 57 korda suurem kui Maa, kuid p\u00f6\u00f6rleb \u00fcsna kiiresti \u2013 \u00fcks p\u00e4ev kestab vaid 16 tundi ja 7 minutit. Selle keskmine kaugus P\u00e4ikesest on umbes 4 500 miljonit km ja \u00fcks aasta Neptuunil kestab peaaegu 165 Maa-aastat.<\/p>\n

Nagu Uraanil, koosneb ka selle atmosf\u00e4\u00e4r vesinikust, heeliumist ja metaanist. Selle sisemus koosneb j\u00e4\u00e4st, millel v\u00f5ib olla kivine tuum. Kuigi atmosf\u00e4\u00e4r on v\u00e4ga k\u00fclm (-220 \u00b0C), esineb sinisel planeedil v\u00e4ga tugevaid tuuli ja \u00e4gedaid torme. Voyager 2 pildistas tohutu laigu, mis oli Maa suurusega.<\/p>\n

Neptuunil on v\u00e4hemalt viis tumedat, kitsast r\u00f5ngast (mis on nimetatud Galle\u2019i, Le Verrier\u2019i, Adamsi ja teiste selle planeedi avastamisele kaasa aidanud isikute j\u00e4rgi).<\/p>\n

Sellel on 13 teadaolevat kuud. Kaugelt suurim neist on Triton \u2013 j\u00e4ine maailm, mis on suurem kui Pluuto. Tritonil on v\u00e4ga k\u00fclm, mist\u00f5ttu on selle \u00f5huke atmosf\u00e4\u00e4r pinnale k\u00fclmunud. Siiski on seal palju aktiivseid j\u00e4\u00e4vulkaane, mis paiskavad \u00f5hku gaasi- ja tolmupilvi. Triton on ebatavaline ka selle poolest, et ta tiirleb Neptuuni \u00fcmber \u201cvales suunas\u201d (idast l\u00e4\u00e4nde). Tundub, et Neptuuni gravitatsioon on ta ammu endasse haaranud.<\/p>","protected":false},"excerpt":{"rendered":"
