2019 Mercury transit across the Sun

mercury-transit-2019

Skywatchers around the world witnessed a rare celestial event on November 11, 2019 – planet Mercury moving across the face of the Sun.  From the perspective of humans on Earth, Mercury spent 5.5 hours crossing in front of the face of the Sun. This is the last Mercury transit until 2032.

European Space Agency's (ESA) Proba-2 and NASA's Solar Dynamics Observatory (SDO) had a "ring-side seat" for the rare transit, capturing planet Mercury as a small black disc, moving from left to right.

The planet's silhouette began to advance to the Sun's disk at 12:35 UTC – it was when the Sun was over the horizon for viewers in South America, eastern Central America, and the U.S. East Coast.

For viewers in the rest of the U.S., Mercury was already hovering across the Sun by sunrise.

For watchers in most of Africa and Europe, Mercury was still moving across the Sun as it dipped below the western horizon.

A solar transit is when a celestial body is seen passing across the solar disc from the Earth's perspective.

Mercury undergoes around 13 transits every 100 years, the last one being in 2016.
