Simultaneous occurrence of solar eclipse and transit of Mercury
8059 Jul 20
Transit of Mercury and Annular Solar Eclipse as seen from location of Greatest Eclipse
23° S from the Equator
The next time a central (total, annular or hybrid) eclipse of the Sun is predicted to occur during a transit of an inner planet is on July 20, 8059. This document presents some data for both phenomena. During the period 50 000 BC - 50 000 AD only 29 central eclipses are confirmed to occur during a planetary transit, previous one on 27 Aug 11436 BC and following one on 04 Aug 9361 (both involving Mercury as well). Due to uncertainty in ΔT any prediction of where eclipse and transit will be observable is completely unreliable.

Notes
1 This value would be the true value if difference between UT and TT is integer number of sidereal days (86,164.09s). For every 4 seconds of deltaT the location is displaced eastwards by a little more than 1'. However by the year of eclipse difference between UT and TT will be several days, equaling thousands of degrees displacement, and worst of all - uncertainty of the actual displacement is hundreds of degrees, practically giving us no idea in which area eclipse will take place.
