Neptun je leta 1846 odkril Johann Galle, astronom na berlinskem observatoriju. Galle je vedel, kam naj gleda, zahvaljujo\u010d izra\u010dunom francoskega matematika Urbaina Le Verrierja. Tako Le Verrier kot John Adams v Angliji sta ugotovila, da neznani planet vpliva na Uran, zaradi \u010desar ta upo\u010dasnjuje ali pospe\u0161uje svojo gibanje.<\/p>\n<\/div>\n

Neptun se je izkazal za skoraj identi\u010dnega dvojnika Urana. Je 57-krat ve\u010dji od Zemlje, vendar se vrti precej hitro \u2013 en dan traja le 16 ur in 7 minut. Njegova povpre\u010dna razdalja od Sonca je pribli\u017eno 4.500 milijonov km, eno leto na Neptunu pa traja skoraj 165 zemeljskih let.<\/p>\n

Tako kot Uran ima tudi ta planet atmosfero, sestavljeno iz vodika, helija in metana. Njegovo notranjost sestavljajo ledovi, morda pa ima tudi kamnito jedro. \u010ceprav je atmosfera zelo mrzla (-220 stopinj Celzija), na tem modrem planetu pihajo zelo mo\u010dni vetrovi in divjajo hude nevihte. Sonda Voyager 2 je posnela ogromno liso, veliko kot Zemlja.<\/p>\n

Neptun ima vsaj pet temnih, ozkih obro\u010dev (poimenovanih po Galleju, Le Verrierju, Adamsu in drugih, ki so sodelovali pri odkritju tega planeta).<\/p>\n

Ima 13 znanih lun. Dale\u010d najve\u010dja je Triton, leden svet, ki je ve\u010dji od Plutona. Na Tritonu je zelo mrzlo, zato se je njegova redka atmosfera zamrznila na povr\u0161ini. Vendar pa ima veliko aktivnih ledenih vulkanov, ki bruhajo oblake plina in prahu. Triton je nenavaden tudi zato, ker se giblje okoli Neptuna v \u201cnapa\u010dni smeri\u201d (z vzhoda proti zahodu). Zdi se, da ga je Neptunova gravitacija ujel \u017ee davno.<\/p>","protected":false},"excerpt":{"rendered":"
