Watch Mercury travel across the face of the Sun (VIDEO)
It only happens a few times a century: the smallest planet in our solar system is passing between the Earth and the Sun, allowing us a rare glimpse of Mercury in motion.
The planet appears as a small black dot against the bright background of the Sun, traveling diagonally in front of the solar sphere over several hours today.
