Neptun a fost descoperit \u00een 1846 de Johann Galle, astronom la Observatorul din Berlin. Galle \u0219tia unde s\u0103 caute datorit\u0103 calculelor efectuate de matematicianul francez Urbain Le Verrier. At\u00e2t Le Verrier, c\u00e2t \u0219i John Adams din Anglia \u00ee\u0219i d\u0103duser\u0103 seama c\u0103 o planet\u0103 nev\u0103zut\u0103 exercita o for\u021b\u0103 de atrac\u021bie asupra lui Uranus, determin\u00e2nd-o s\u0103-\u0219i \u00eencetineasc\u0103 sau s\u0103-\u0219i accelereze mi\u0219carea.<\/p>\n<\/div>\n

Neptun s-a dovedit a fi aproape un geam\u0103n identic al lui Uranus. Este de 57 de ori mai mare dec\u00e2t P\u0103m\u00e2ntul, dar se rote\u0219te destul de repede \u2013 o zi dureaz\u0103 doar 16 ore \u0219i 7 minute. Distan\u021ba medie fa\u021b\u0103 de Soare este de aproximativ 4.500 de milioane de km, iar un an pe Neptun dureaz\u0103 aproape 165 de ani terestri.<\/p>\n

La fel ca Uranus, are o atmosfer\u0103 format\u0103 din hidrogen, heliu \u0219i metan. Interiorul s\u0103u este alc\u0103tuit din ghea\u021b\u0103, cu un posibil nucleu st\u00e2ncos. De\u0219i atmosfera este foarte rece (-220 de grade Celsius), planeta albastr\u0103 are v\u00e2nturi foarte puternice \u0219i furtuni violente. Voyager 2 a fotografiat o pat\u0103 uria\u0219\u0103, de m\u0103rimea P\u0103m\u00e2ntului.<\/p>\n

Neptun are cel pu\u021bin cinci inele \u00eentunecate \u0219i \u00eenguste (numite dup\u0103 Galle, Le Verrier, Adams \u0219i al\u021bi cercet\u0103tori care au contribuit la descoperirea planetei).<\/p>\n

Are 13 luni cunoscute. De departe cea mai mare este Triton, o lume \u00eenghe\u021bat\u0103 mai mare dec\u00e2t Pluto. Triton este foarte rece, a\u0219a c\u0103 atmosfera sa sub\u021bire s-a \u00eenghe\u021bat pe suprafa\u021b\u0103. Cu toate acestea, are numero\u0219i vulcani de ghea\u021b\u0103 activi care arunc\u0103 jeturi de gaz \u0219i praf. Triton este, de asemenea, neobi\u0219nuit deoarece se \u00eenv\u00e2rte \u201c\u00een sens invers\u201d (de la est la vest) \u00een jurul lui Neptun. Se pare c\u0103 a fost capturat de gravita\u021bia lui Neptun cu mult timp \u00een urm\u0103.<\/p>","protected":false},"excerpt":{"rendered":"
