When an inner planet (Mercury or Venus) passes between the Earth and the Sun and is in the plane of the Earth's orbit, the dark outline of the planet can be seen against the image of the Sun. These events are rare. The last time the Transit of Mercury was visible form North America was 26 years ago. Transits of Venus are even more rare. The last Venusian transit was in 1882. The next one will be 8 June 2004 and another on 6 June 2012.

On 15 November 1999, Mercury passed between the Earth and the Sun in the plane of the Earth's orbit. The transit started approximately 2:11 PM MST and last just under one hour.
