Mercury Transit

The most recent Mercury transit occurred on November 11, 2019. During this event, Mercury passed between the Earth and the Sun, appearing as a small black dot moving across the Sun's surface as observed from Earth. This phenomenon is relatively rare and happens only about 13 times per century on average.

Certainly! A "Mercury transit" refers to the event when the planet Mercury passes directly between the Earth and the Sun, as observed from Earth. This rare astronomical occurrence is similar to a solar eclipse, but instead of the Moon blocking the Sun, it's the much smaller planet Mercury.

During a Mercury transit, observers on Earth can see Mercury as a small, dark disk slowly moving across the face of the Sun. It appears as a tiny black dot against the Sun's bright disk.
