On 8 June 2004,Venus will pass directly between Earth and the Sun. Local weather conditions permitting, this “transit of Venus” will be visible in its entirety over much of Europe and Asia, from London to Beijing. In London, the times of the first and last contacts will be 05:19:52 and 11:23:16 Universal Time, respectively—just over 6 hours from start to finish. In Sydney and Tokyo, only the ingress of the planet will be visible before sunset, and residents of Buenos Aries, Toronto, and New York will have to be up early to see the final contact. Another transit will occur on 6 June 2012, and then there will be no more transits until 11 December 2117 and 8 December 2125 [Moor, 2000].
