   Jun 5, 2012 · Transits of Venus are very rare, separated by more than a hundred years. There have been 53 transits since 2000 B.C., but only six have been witnessed since the invention of the telescope in 1608. These rare events occur in pairs, with the first transit occurring June 8, 2004. The next opportunity won't be until Dec. 10 and 11, 2117.
