A transit of Venus across the Sun takes place when the planetVenus passes directly between the Sun and Earth. It is one of the rarest predictable astronomical phenomena and happens in pairs eight years apart that are separated from each other by 105 or 121 years. The last transit before 2012 was in 2004, and the next pair of transits will occur in 2117 and 2125.
