The transit was a very rare astronomical event that would not be seen again for another 105 years.
Observers in north and central America, and the northern-most parts of South America saw the event start just before local sunset.
The far northwest of America, the Arctic, the western Pacific, and east Asia witnessed the entire passage.
While the UK and the rest of Europe, the Middle East, and eastern Africa waited for local sunrise to try to see the closing stages of the transit.
Venus appeared as a small black dot moving slowly but surely across the solar disc. The traverse lasted more than six and a half hours.
