Per explicar-ho breument es tracta d’un eclipsi de Sol per part de Mercuri que s’interposa entre el Sol i la Terra, el que passa \u00e9s que, a difer\u00e8ncia d’un eclipsi de Lluna, on el cercle solar queda tapat, en el cas de Mercuri es veu com un min\u00fascul punt negre travessant el Sol i que passaria totalment desapercebut a no ser que un tingui informaci\u00f3 que pot ser observat.<\/p>\n

Per con\u00e8ixer una mica m\u00e9s el nostre Sistema Solar, dir que \u00fanicament tres astres naturals (descomptant asteroides d’\u00f2rbita interior) poden interposar-se entre nosaltres i el Sol un \u00e9s sabut la Lluna (eclipsis de Sol) i els altres s\u00f3n els planetes interiors a l’\u00f2rbita de la Terra: Mercuri i Venus, que realitzen el que coneixem com a tr\u00e0nsits.<\/p>\n

Si el temps acompanya (bon sol) intentarem projectar la imatge del Sol i visualitzar el planeta Mercuri travessant el Sol. Tamb\u00e9 hi ha adreces web que faran el seguiment per v\u00eddeo per qui estigui encuriosit. El tr\u00e0nsit comen\u00e7a a les 13:35 hora oficial i no podrem observar el final ja que ser\u00e0 m\u00e9s tard de la posta de Sol. Per tant,\u00a0 parlem d’un fenomen que dura cinc hores i mitja si el pogu\u00e9ssim observar amb totalitat.<\/p>\n

Haurem d\u2019esperar al 13 de novembre de 2032 per observar el seg\u00fcent tr\u00e0nsit de Mercuri que tamb\u00e9 ser\u00e1 visible des d\u2019Europa.<\/p>\n
