Venus usually passes under or over the sun in its diagonal orbit, but there are two points in its orbit when it passes directly in front of the sun in its 225 day orbit, but the Venus transit only happens when Venus, Earth and the Sun directly line up as shown in this diagram.
The top shows Venus on its normal orbit and the bottom shows the Venus transit.
This will be an amazing spectacle lets hope it gets broadcast for all to see, as it will be 105 years till it happens again, in 2117, and then it will happen again in 8 years at 2125, and will go on and on for a very long time going 105 years then 8 years 105 years 8 years and on and on. The last time it happened was June 8th 2004, and the first recorded time was November 23 1396, people believe that Aztec astronomers may have seen this transit.
