Sistemul Solar este format din Soare \u0219i din toate obiectele mai mici care se mi\u0219c\u0103 \u00een jurul acestuia. \u00cen afar\u0103 de Soare, cele mai mari corpuri din Sistemul Solar sunt cele opt planete principale. Cele mai apropiate de Soare sunt patru planete st\u00e2ncoase, relativ mici: Mercur, Venus, P\u0103m\u00e2ntul \u0219i Marte.<\/p>\n<\/div>\n

Dincolo de Marte se afl\u0103 centura de asteroizi \u2013 o regiune populat\u0103 de milioane de corpuri rocose. Acestea sunt r\u0103m\u0103\u0219i\u021be ale form\u0103rii planetelor, de acum 4,5 miliarde de ani.<\/p>\n

Dincolo de centura de asteroizi se afl\u0103 cele patru planete gigantice gazoase \u2013 Jupiter, Saturn, Uranus \u0219i Neptun. Aceste planete sunt mult mai mari dec\u00e2t P\u0103m\u00e2ntul, dar foarte u\u0219oare \u00een raport cu dimensiunile lor. Ele sunt alc\u0103tuite \u00een mare parte din hidrogen \u0219i heliu.<\/p>\n

P\u00e2n\u0103 de cur\u00e2nd, cea mai \u00eendep\u0103rtat\u0103 planet\u0103 cunoscut\u0103 era o lume \u00eenghe\u021bat\u0103 numit\u0103 Pluto. Cu toate acestea, Pluto este mult mai mic\u0103 dec\u00e2t Luna P\u0103m\u00e2ntului, iar mul\u021bi astronomi consider\u0103 c\u0103 este prea mic\u0103 pentru a fi numit\u0103 o planet\u0103 adev\u0103rat\u0103.<\/p>\n

\u00cen 2005, a fost descoperit un obiect numit Eris, care este cel pu\u021bin la fel de mare ca Pluto, la o distan\u021b\u0103 foarte mare de Soare. \u00cen ultimii ani, au fost descoperite peste 1.000 de lumi \u00eenghe\u021bate, precum Eris, dincolo de Pluto. Acestea sunt denumite obiecte din Centura Kuiper. \u00cen 2006, Uniunea Astronomic\u0103 Interna\u021bional\u0103 a decis c\u0103 Pluto \u0219i Eris trebuie clasificate drept \u201cplanete pitice\u201d.<\/p>\n

\u0218i mai departe se afl\u0103 cometele din Norul Oort. Acestea sunt at\u00e2t de \u00eendep\u0103rtate \u00eenc\u00e2t nu pot fi observate nici m\u0103car cu cele mai mari telescoape. Din c\u00e2nd \u00een c\u00e2nd, una dintre aceste comete este perturbat\u0103 \u0219i se \u00eendreapt\u0103 spre Soare. Atunci devine vizibil\u0103 pe cerul nop\u021bii.<\/p>","protected":false},"excerpt":{"rendered":"
