Born on this day in 1738, sir william herschel discovered which planet which he originally named “georgium sidus”?

The correct answer for this question would be the planet URANUS. Sir William Herschel discovered Uranus and he originally named it Georgium Sidus. He was a British astronomer and composer of German origin, and brother of fellow astronomer Caroline Herschel, with whom he worked. He discovered Uranus in the 13th of March 1781. Hope this answer helps.
