Transit of Uranus from Neptune I would like to help find sources or calculations for the following dates found in Wikipedia (in French). The next Uranus transit from Neptune will happen :
1. October   38172
2. August   111551
3. November 124067

Would you please help me find sources or calculations stating these three dates?
The only one who seems legit is the first date, October 38172. It appears somewhere in Transits, by Jean Meeus (1989), and some say that also in the SOLET webpage, but I can't find it either. Taking into account that, if true, it comes from a book from 1989 and probably is not very accurate, I wouldn't take that date as an exact thing.
The other dates I can't find anything.
