Hamilton or Mikromarius has a post on this topic, not sure of what he called it, but do a search on his name, you might find it.

You *are* aware that Venus transits the sun frequently, right?
It's a planet, it has a regular orbit which goes around the sun in a shorter time period than the Earth does. There've been others in the past (and a second transit follows 8 years after the initial event.) We'll see another one in 2012.

Transits of Venus have been observed only in 1639, 1761, 1769, 1874, and 1882, and in the 18th century were the main way that the size and scale of the solar system were obtained. They also occured at other times in history... they just weren't observed.

It's a planet, for Pete's sakes. It's in an orbit. It'll do this sort of thing until the sun swallows it in the red giant phase some 4 or 5 billion years from now.
