Mercury just passed Sun, and we saw it from Earth!
For the last time in this decade, Mercury has passed in front of the Sun in what’s known as a transit – a rare chance to see a planet crossing the face of the Earth.
The transit would happen again in 20132, and maybe visible from Asia and Australia also. And though it was a treat for North America as the transit was visible from there, North America won’t get another shot until 2049.
With roughly 13 transits of Mercury happening in an entire century, it’s a rare treat indeed. Four of these events have occurred in this decade.
DescriptionMercury is the smallest and innermost planet in the Solar System. Its orbit around the Sun takes only 87.97 days.
