Trânsito Solar de Vénus 2012

Venus Solar Transit 2012

Date of Issue : 27 June 2012

The transits of Venus are very rare astronomical phenomena. When the Sun, Venus and Earth are in a near-perfect alignment we can see, with the appropriate instruments, a small black disk – the silhouette of Venus – crossing the bright disk of the Sun. The transits of Venus occur in pairs in eight year intervals. In turn, each of these pairs occurs, alternately, every 105.5 and 121.5 years. The last transit of Venus occurred on the morning of June 8th, 2004 and was fully visible in mainland Portugal (only its beginning was not observed in the Azores and Madeira), for more than six hours.
It’s just that the next Venus transit will only be seen from the Earth on December 11th, 2117.
