Next Transit of Mercury: 2016 May 9

Transits of Mercury are occuring more often than transits of Venus at irregular intervalls of 3.5 to 13 years.

On this day half our globe will be able to watch the tiny black dot of the planet Mercury moving across the disc of the sun. Given a cloudless sky, you'll need binoculars or a small telescope and a sun filter to follow the spectacle for several hours.

The previous transit of Mercury occurred on November 15, 1999.
