Urano has been discovered on 13 March 1781 from William Herschel. The galileian telescope was invented on 1608 from Hans Lippershey. Now I have a doubt: on 25 January 1590 was one close conjunction 0.08° (www.pierpaoloricci.it/dati/triipia_eng.htm) between Mars-Venus-Uranus. Since the first two planets were known from the antiquity, and that in that day Urano had a magnitudine 5,9, it is possible that figures however in some cronaca?
