PER QU\u00c8 GIREN ELS PLANETES AL VOLTANT DEL SOL?<\/i><\/b><\/p>\n

 <\/p>\n

Tot \u00e9s degut a la for\u00e7a gravitat\u00f2ria! Com va anotar Isaac Newton, com m\u00e9s gran \u00e9s un cos, m\u00e9s for\u00e7a de gravetat t\u00e9. Per tant, el Sol, que \u00e9s molt m\u00e9s gran que la resta dels planetes de la nostra gal\u00e0xia, t\u00e9 molta m\u00e9s for\u00e7a de gravetat, la qual cosa \u00e9s la causant de que tots els planetes girin al seu voltant.<\/span><\/p>\n

 <\/p>\n

Sab\u00edeu que tot i que ajunt\u00e9ssim tots els planetes de la nostra gal\u00e0xia, encara continuem sent molt m\u00e9s petits que el Sol?<\/span><\/p>\n

 <\/p>\n

I que cada planeta triga un temps diferent en fer el moviment de translaci\u00f3! Tot dep\u00e8n de la proximitat al Sol. Com m\u00e9s a prop est\u00e0 , menys temps triga. Per tant, Mercuri, que \u00e9s el que m\u00e9s a prop del Sol est\u00e0,\u00a0 \u00e9s el que menys triga amb 88 dies i Nept\u00fa, que \u00e9s el que m\u00e9s lluny est\u00e0, \u00e9s el que m\u00e9s triga, amb 60.190 dies!<\/span><\/p>\n

I per suposat, hem vist el moviment de translaci\u00f3 de la Terra, que el fa en 365 dies, un any terrestre!<\/span><\/p>\n

 <\/p>\n

Ens ha mostrat que el moviment dels planetes al voltant del sol t\u00e9 forma d\u2019el\u00b7lipse!\u00a0<\/span><\/p>\n

 <\/p>\n

I aprofitant la presentaci\u00f3 del Leo, observant l\u2019el\u00b7lipse de la translaci\u00f3 de la Terra, per qu\u00e8 hi ha les estacions de l\u2019any. Aix\u00f2 \u00e9s degut a la proximitat i inclinaci\u00f3 de la Terra vers al Sol.<\/span><\/p>\n

 <\/p>\n

Gr\u00e0cies Leo!<\/span><\/p>\n
