This is probably how Uranus was first spotted in the sky in the first place: when it's in opposition, shining as we are in the way between it and our shared Sun, so closest. But that happens annually. We're hearing about it now because Uranus is in Taurus... again.
In 1690, Flamsteed marked it as "34 Tauri". Every 84 years, it returns to Taurus. It is in Taurus, it seems, it is most visible. In 1775ish it should have been visible there again; Pierre-Charles Le Monnier saw it 1750 through 1769 but didn't connect it to old 34 Tauri (interestingly, by then returning to Tauri). William Herschel, it seems, took the measurements of the thing 1781 - on its way out of its 1690 position - and noticed it looked more like a comet than a star.
I don't know why the Seventh Planet be most-visible when it sails through Taurus, of all zodiacal/elliptic constellations. Darker over there?
