Hello! This is a note to let the editors of this article know that File:Mercury transit 2.jpg will be appearing as picture of the day on November 7, 2011. You can view and edit the POTD blurb at Template:POTD/2011-11-07. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page so Wikipedia doesn't look bad. :) Thanks! howcheng { chat} 19:57, 4 November 2011 (UTC)
Last transit Nov 2006. Next transit May 2016. That is 9.5 years. Therefore why does article state transits only occur every 7, 13 or 33 years - or are the dates wrong?
"November transits occur at intervals of 7, 13, or 33 years ; May transits only occur at intervals of 13 or 33 years. The last three transits occurred in 1999, 2003 and 2006 ; the next will occur in 2016."

I entered an item twice then mistakenly deleted someone else's comment instead of my repeated entry. Now I cant find that deleted item to reinstate it, as there appears to be no history section for discussion items. Sorry. Tiddy ( talk) 01:45, 16 November 2011 (UTC)
I changed the years of simultaneous Mercury and Venus transits. The numbers were mangled. The text The last simultaneous transit occurred in 373173 BC showed 373,173 BC which was very confusing it could mean both the years 373 and 173 BC. The macro {{{formatnum}}} issues wrong results as it does not observe ISO standards which prescribe spaces rather than commas as thousands separator. More Wikipedia pages have this error.

Hallo everyone. Read also https://en.wikipedia.org/?title=Transit_of_Mercury&oldid=726166700 Greetings of Nico from Gouda, the Netherlands. 84.80.54.162 ( talk) 15:56, 5 July 2016 (UTC)
After about the year +12,000 the backwards motion of the descending node of the orbit of Mercury as seen from the Earth will change in a forward motion and this means that then after each 217 year the chords of the transits of Mercury on the solar disc will move Southwards instead of Northwards (which it nowadays does).
For example 217 years series #2: Please note: only each tenth transit of this series is listed, thus after each 10 x 217 years = 2170 years.
1937/05/11 - 0.26544 (first transit of this 217 years series) 4107/06/05 - 0.20290 6277/06/29 - 0.15319 8447/07/24 - 0.11838 10617/08/18 - 0.09853 12787/09/13 - 0.09382 14957/10/08 - 0.10249 17127/11/03 - 0.12260 19297/11/27 - 0.15251 21467/12/25 - 0.18880 23638/01/19 - 0.22914 25591/02/12 - 0.26797 (last transit of this 217 years series, after 9 instead of 10 x 217 years)
The solar radius is about 0.2700 during each transit and always Mercury will pass South of the midpoint of the solar disc. From -50,000 till +50,000 there will be about +42,000 a second 'turningpoint' of the Marcury transits at the descending node and from then it will moves backwards again just as it nowadays does as seen from the Earth. Source: http://www.solexorb.it/SolexOld/ and then click on Mercury.
Please note: The pair of May transits 1937/05/11 - 1957/05/06 which ends in 2588/05/17 - 2608/05/13 (217 years series #20 will then end) returns in 14740/10/05 - 14760/10/01 (217 years series #20 will then restart).
Before about the year -9000 the forward motion of the ascending node of the orbit of Mercury as seen from the Earth was changed in a backwards motion and this means that then after each 217 year the chords of the transits of Mercury on the solar disc moved Southwards instead of Northwards (which it nowadays does).
For example 217 years series #1:
-22739/07/10 - 0.27003 (first transit of this 217 years series) After 4 x 217 years = 868 years -21871/07/14 - 0.25833 From now after each 10 x 217 years = 2170 years -19701/07/24 - 0.23217 -17531/08/03 - 0.20926 -15361/08/13 - 0.19001 -13191/08/23 - 0.17436 -11021/09/02 - 0.16312 -8851/09/12 - 0.15789 -6681/09/23 - 0.15941 -4511/10/02 - 0.17031 -2341/10/13 - 0.19115 -171/10/23 - 0.22304 1999/11/15 - 0.26750 (last transit of this 217 years series)
Please note: before 1582 the Julian Calendar is used! The solar radius is about 0.2700 during each transit and always Mercury will pass North of the midpoint of the solar disc.
Because both nodes are turning forward and backwards in direction in time, a 217 years series can last about 50,000 years! For example the 217 years series of which the november transit of 1914/11/07 is a member of it, began on -35410/05/06 and will end on 14284/04/05. But from -50,000 till +50,000 there are NO more 'turningpoints' of the transits of Mercury at the ascending node as seen from the Earth.

Because the 217 year timeperiod is very more accuracy than the wellknown 46 years timeperiod, you can add an extra column on http://fourmilab.ch/documents/canon_transits/ and then click in the Transit Index Table on 40540, you get then this table below. But unfortunately in this table non-central transits such in 1937 and 2608 (2608 is the last one of the 217-yearsseries #20) are NOT listed! Please note: after the year -1 follows the year 1 in this long table! But on https://eclipse.gsfc.nasa.gov/transit/catalog/MercuryCatalog.html fortunately the transit of 1937 is listed.

and so on. (b = (re)begin of a new 217 year-series Mercury-transits, e = the (re)end of an old 217 year-series Mercury-transits)
The number of the nowadays May-transits in 217 years is nowadays slowly increasing:
Two transits in 20 years:
not before the pairs 155 (the re-begin of the 217 years series #4) - 175 and 372 - 392 (the re-end of the 217 years series #22)(2x), and then followed by 1937 (the re-begin of the 217 years series #2) - 1957 till 2588 - 2608 (the re-end of the 217 years series #20)(4x), and then followed by 3936 (the re-begin of the 217 years series #0) - 3956 till 6106 - 6126 (the re-end of the 217 years series #18)(11x) and then followed from the pair 6152 (the re-begin of the 217 years series #-2) - 6172 till far after 12,000.
At the nowadays November transits at the ascending node of the orbit of Mercury: If a new 217 year series has began, the next 217 year series will begin after .x217 years - 46 years. At the nowadays May transits at the descending node of the orbit of Mercury: If a new 217 year series has began, the next 217 year series will begin after .x217 years + 46 years.

In response to the ITN nomination, I've gone through the article and added {{cn}} tags. I count 36 of them now, in virtually every section. Someone interested will have to fix it. starship .paint ( talk) 14:49, 12 November 2019 (UTC)

Last transit Nov 2006. Next transit May 2016. That is 9.5 years. Therefore why does article state transits only occur every 7, 13 or 33 years - or are the dates wrong?
"November transits occur at intervals of 7, 13, or 33 years ; May transits only occur at intervals of 13 or 33 years. The last three transits occurred in 1999, 2003 and 2006 ; the next will occur in 2016."

After about the year +12,000 the backwards motion of the descending node of the orbit of Mercury as seen from the Earth will change in a forward motion and this means that then after each 217 year the chords of the transits of Mercury on the solar disc will move Southwards instead of Northwards (which it nowadays does).
For example 217 years series #2: Please note: only each tenth transit of this series is listed, thus after each 10 x 217 years = 2170 years.
1937/05/11 - 0.26544 (first transit of this 217 years series) 4107/06/05 - 0.20290 6277/06/29 - 0.15319 8447/07/24 - 0.11838 10617/08/18 - 0.09853 12787/09/13 - 0.09382 14957/10/08 - 0.10249 17127/11/03 - 0.12260 19297/11/27 - 0.15251 21467/12/25 - 0.18880 23638/01/19 - 0.22914 25591/02/12 - 0.26797 (last transit of this 217 years series, after 9 instead of 10 x 217 years)
The solar radius is about 0.2700 during each transit and always Mercury will pass South of the midpoint of the solar disc. From -50,000 till +50,000 there will be about +42,000 a second 'turningpoint' of the Marcury transits at the descending node and from then it will moves backwards again just as it nowadays does as seen from the Earth.

Before about the year -9000 the forward motion of the ascending node of the orbit of Mercury as seen from the Earth was changed in a backwards motion and this means that then after each 217 year the chords of the transits of Mercury on the solar disc moved Southwards instead of Northwards (which it nowadays does).
For example 217 years series #1:
-22739/07/10 - 0.27003 (first transit of this 217 years series) After 4 x 217 years = 868 years -21871/07/14 - 0.25833 From now after each 10 x 217 years = 2170 years -19701/07/24 - 0.23217 -17531/08/03 - 0.20926 -15361/08/13 - 0.19001 -13191/08/23 - 0.17436 -11021/09/02 - 0.16312 -8851/09/12 - 0.15789 -6681/09/23 - 0.15941 -4511/10/02 - 0.17031 -2341/10/13 - 0.19115 -171/10/23 - 0.22304 1999/11/15 - 0.26750 (last transit of this 217 years series)

The number of the nowadays November-transits in 217 years is nowadays slowly decreasing:

and so on. (b = (re)begin of a new 217 year-series Mercury-transits, e = the (re)end of an old 217 year-series Mercury-transits)
The number of the nowadays May-transits in 217 years is nowadays slowly increasing:
Two transits in 20 years:
not before the pairs 155 (the re-begin of the 217 years series #4) - 175 and 372 - 392 (the re-end of the 217 years series #22)(2x), and then followed by 1937 (the re-begin of the 217 years series #2) - 1957 till 2588 - 2608 (the re-end of the 217 years series #20)(4x), and then followed by 3936 (the re-begin of the 217 years series #0) - 3956 till 6106 - 6126 (the re-end of the 217 years series #18)(11x) and then followed from the pair 6152 (the re-begin of the 217 years series #-2) - 6172 till far after 12,000.
At the nowadays November transits at the ascending node of the orbit of Mercury: If a new 217 year series has began, the next 217 year series will begin after .x217 years - 46 years. At the nowadays May transits at the descending node of the orbit of Mercury: If a new 217 year series has began, the next 217 year series will begin after .x217 years + 46 years.

In response to the ITN nomination, I've gone through the article and added {{cn}} tags. I count 36 of them now, in virtually every section. Someone interested will have to fix it. starship .paint ( talk) 14:49, 12 November 2019 (UTC)
