Transits of Venus such as the one which occurred a couple days ago come in pairs occurring eight years apart. The last one was in 2004.
The previous pair of transits was in 1874 and 1882, and the next ones won't come until 2117 and 2125.
Besides its astronomical significance, the event carries astrological implications. The transit of the ancient love goddess across the solar face marks a period of heightened awareness, and greater than usual pressure being brought to bear upon human relationships. Therefore, the time of Venus's transit is a momentous and remarkable time.
