I have just been reading the June BAA Journal which arrived this
morning.
Apparently in the year 571,741 there will be a simultaneous transit of
Earth
and Venus, as viewed from Mars.

Not sure whether this is AD or not.

Brings up an interesting point- would a simultaneous transit of Venus
and Mercury as seen from Earth be possible?
If so, how often would it occur?
When's the next one? :-)

The same JBAA article identifies a number of simultaneous Mercury/Venus
transits but none of course in the near future. Transits coinciding with
solar eclipses (and one with a lunar eclipse, visible from the moon) are
also identified.


It's fun putting the dates for those into Bill Gray's Guide and being
able to "watch" them (one was actually discovered using Guide)
Unfortunately Guide can't cope with five-figure dates (let alone six
figure) so you can't view the simultaneous events.
