This happened on the days of June 5 and 6, 2012. The last transit happened on June 8, 2004. This will be the planet's last transit this century as the next would occur in December 2117.
Aside from the "Supermoon" phenomenon this is one of the rare events that also caught the world's attention.
As the planetary distance counts thousands to millions of miles from each other, this event is different from the solar eclipse when the moon comes between the sun and the earth, Venus looks like a small dot on the Sun's surface.
This can not be seen directly as the sun would damage vision and proper solar photography techniques can capture stunning images such one above.
