Mercury Transit 2019 - 4K

A Mercury transit refers to the event when the planet Mercury passes directly between the Earth and the Sun. During this event, Mercury can be seen as a small black dot moving across the face of the Sun. Transits of Mercury are relatively rare, occurring about 13 times per century. They are fascinating astronomical events that allow astronomers to study the planet's atmosphere, temperature, and other characteristics. It is important to note that observing a Mercury transit requires proper solar viewing equipment to protect your eyes, as looking directly at the Sun can cause severe eye damage.
