Venus transits across the sun

It's a spectacle that won't repeat for another century - the sight of Venus slowly inching across the face of the sun.
Venus transits across the sun
None of us will likely see Venus pass, like a moving beauty spot, across the face of the sun again.

From the U.S. to South Korea, people around the world turned their attention to the daytime sky on Tuesday and early Wednesday in Asia to make sure they caught the rare sight of the transit of Venus. The next one won't be for another 105 years.

On June 5-6 2012, SDO is collecting images of one of the rarest predictable solar events: the transit of Venus across the face of the sun. This event happens in pairs eight years apart that are separated from each other by 105 or 121 years. The last transit was in 2004 and the next will not happen until 2117. (NASA Photo)

Venus transits across the sun
Venus, which is extremely hot, is one of Earth's two neighbours and is so close in size to our planet that scientists at times call them near-twins. During the transit, it will appear as a small dot.

Venus transits across the sun
This will be the seventh transit visible since German astronomer Johannes Kepler first predicted the phenomenon in the 17th century. Because of the shape and speed of Venus' orbit around the sun and its relationship to Earth's annual trip, transits occur in pairs separated by more than a century.
