Venus will cross the disc of the Sun on 2125 December 8th. The map above shows the visibility of the event.
The geocentric circumstances of the transit are shown in the diagram to the right. During the transit, the diameter of the Sun is 1948.0 arcseconds and that of Venus is 63.1 arcseconds. In other words, the diameter of Venus is 0.03 that of the Sun, making it look like a rapidly moving sunspot. The minimum separation between the centre of the solar disc and Venus is 736.4 arcseconds. The whole transit lasts just over five and a half hours.
All timings are given in Terrestrial Time (TT), as accurate predictions of
the Earth's rotation cannot be made for more than a few years into the future.
