Transition of Mercury

A Mercury transit refers to the event when the planet Mercury passes directly between the Earth and the Sun. During a Mercury transit, observers on Earth can see Mercury as a small, dark dot moving across the Sun's surface. These transits are relatively rare and occur about 13 times a century. The last Mercury transit occurred on November 11, 2019, and the next one will take place on November 13, 2032. Observing a Mercury transit requires proper solar viewing equipment to protect your eyes from the Sun's intense radiation.
