Las im\u00e1genes enviadas por naves espaciales como la Mars Express de la ESA muestran que Marte tiene muchos cr\u00e1teres de impacto de gran tama\u00f1o. La mayor\u00eda de ellos se encuentran al sur del ecuador. Parece que se formaron por el impacto de meteoritos contra la superficie hace miles de millones de a\u00f1os. El cr\u00e1ter m\u00e1s grande tiene unos 1.800 km de di\u00e1metro, lo suficientemente grande como para tragarse la mitad de Europa.<\/p>\n<\/div>\n

Sin embargo, la superficie de Marte ha cambiado a lo largo de su historia. Una caracter\u00edstica evidente es el enorme sistema de valles \u2014el Valles Marineris\u2014 situado cerca del ecuador del planeta. Con unos 5.000 km de longitud, se extender\u00eda desde Par\u00eds hasta Nueva York.<\/p>\n

Parece que los valles se formaron a ra\u00edz de las grietas que se produjeron en la superficie del planeta, cuando la corteza rocosa se estir\u00f3 y se separ\u00f3. Ahora los valles son tan anchos que una persona que se situara en un extremo no podr\u00eda ver el otro lado.<\/p>\n

No muy lejos, al oeste, hay cinco enormes volcanes. El m\u00e1s impresionante de ellos es el Olympus Mons, el mayor volc\u00e1n del Sistema Solar. Es m\u00e1s ancho que Inglaterra y tres veces m\u00e1s alto que el Monte Everest, la monta\u00f1a m\u00e1s alta de la Tierra. Ninguno de estos volcanes se encuentra hoy en actividad.<\/p>","protected":false},"excerpt":{"rendered":"
