2016 Mercury Transit in

The last Mercury Transit visible from Earth occurred on May 9-10, 2016. During this event, Mercury passed between the Earth and the Sun, appearing as a small black dot moving across the Sun's surface. This phenomenon is relatively rare and can only be observed during specific astronomical alignments. The next Mercury Transit after that was on November 11, 2019.
