Toate planetele se rotesc \u00een jurul Soarelui \u00een sens invers acelor de ceasornic \u2013 privite de deasupra polului nord al P\u0103m\u00e2ntului. Anul lor \u2013 timpul necesar pentru a parcurge o orbit\u0103 complet\u0103 \u2013 variaz\u0103 \u00een func\u021bie de distan\u021ba fa\u021b\u0103 de Soare. Un an pe Mercur dureaz\u0103 doar 88 de zile terestre, a\u0219a c\u0103 cineva n\u0103scut acolo ar avea de patru ori mai multe zile de na\u0219tere dec\u00e2t noi, cei de pe P\u0103m\u00e2nt. \u00cen schimb, un an pe Pluto este egal cu 248 dintre anii no\u0219tri. Cineva n\u0103scut pe Pluto nu \u0219i-ar s\u0103rb\u0103tori niciodat\u0103 ziua de na\u0219tere!<\/p>\n<\/div>\n

Venus \u0219i Mercur nu au sateli\u021bi naturali, dar celelalte \u0219apte planete au toate luni care le \u00eenconjoar\u0103. Num\u0103rul total \u00eenregistrat p\u00e2n\u0103 \u00een prezent este de 138. Majoritatea lunilor sunt foarte mici \u0219i greu de observat, chiar \u0219i cu telescoape mari. \u00cen prezent, recordul \u00eel de\u021bine Jupiter, cu 63 de sateli\u021bi cunoscu\u021bi. Printre ace\u0219tia se num\u0103r\u0103 patru luni de dimensiunea unei planete \u2013 Ganymede (cel mai mare satelit din Sistemul Solar), Callisto, Europa \u0219i Io.<\/p>\n

Gravita\u021bia puternic\u0103 a celorlalte planete gigant gazoase a atras, de asemenea, un num\u0103r mare de sateli\u021bi: Saturn are 31, Uranus 27 \u0219i Neptun 13. At\u00e2t P\u0103m\u00e2ntul, c\u00e2t \u0219i Pluto sunt \u00eenconjura\u021bi de c\u00e2te o lun\u0103 mare.<\/p>\n

Cele patru planete cele mai mari \u2013 Jupiter, Saturn, Uranus \u0219i Neptun \u2013 au, de asemenea, inele. Acestea sunt formate din fragmente de ghea\u021b\u0103 \u0219i roc\u0103, cu dimensiuni variind de la m\u0103rimea unor mun\u021bi p\u00e2n\u0103 la cea a fumului de \u021bigar\u0103. Inelele ar putea fi r\u0103m\u0103\u0219i\u021be ale unei luni care s-a destr\u0103mat sau fragmente desprinse din lunile din apropiere.<\/p>","protected":false},"excerpt":{"rendered":"
