Transit of Mercury across the sun

Because of its close proximity to the sun, Mercury is often lost in the glare and is usually best seen from Earth only when there is a solar eclipse. From the Northern Hemisphere, you can sometimes see it at dawn or twilight. Here Mercury crosses the sun in 2006. Mercury is the small black dot in the lower middle of the sun. The sunspot on the extreme left of the star is actually bigger than the planet.
