Yes, guys, that's me and my late 17th/early 18th century tech trivia. But that seemed to be just too interesting not to miss.
If Flamsteed manages to recognize Uranus as a planet...does it still end up called Uranus? Or maybe Neptune (that's the mother of all allohistoric stuff, I think)?
Considering that OTL Uranus nearly ended up being called Neptune...Swedish astronomer Erik Prosperin proposed the name Neptune, which was supported by other astronomers who liked the idea to commemorate the victories of the British Royal Naval fleet in the course of the American Revolutionary War by calling the new planet even Neptune George III or Neptune Great Britain
