The Full Story
William Herschel discovered Uranus on 13 March 1781, proving it was a new planet and not a fixed star. He later discovered two of its moons, Titania and Oberon, in 1787, and he also contributed to early understanding of the planet’s nature. Uranus was the first planet discovered in modern times, extending the known Solar System. Herschel’s work opened the door to finding much more beyond the traditional naked-eye planets.
