ORANGE, CA - JUNE 5:  The planet Venus passes before the sun, a very rarely-seen event, on June 5, 2012 near Orange, California. The transit of Venus involves the planet Venus crossing in front of the sun. The last time it was seen in California was 1882 and the next pair of events will not happen again until the year 2117 and 2125. The transit of Venus across the sun has been seen only seven times since the telescope was invented. (Photo by David McNew/Getty Images)
