January 6, 1781In the Battle of Jersey, the British defeat the last attempt by France to invade Jersey.
The Battle of Jersey was an attempt by France to invade Jersey and remove the threat the island posed to American shipping in the American War of Independence. Jersey was used as a base for privateering by the British, and France, engaged in the war as an ally of the United States, sent an expedition to gain control of the island. The expedition ultimately failed, and its commander, Baron Phillipe de Rullecourt, died of wounds sustained in the fighting. The battle is often remembered for the death of the British officer Major Pierson, and a painting based on his final moments by John Singleton Copley.

William Herschel discovers Uranus.
Size comparison of Earth and Uranus
Uranus is the seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. It is named after the ancient Greek deity of the sky Uranus, the father of Cronus (Saturn) and grandfather of Zeus (Jupiter). Though it is visible to the naked eye like the five classical planets, it was never recognized as a planet by ancient observers because of its dimness and slow orbit. Sir William Herschel announced its discovery on March 13, 1781, expanding the known boundaries of the Solar System for the first time in modern history. Uranus was also the first planet discovered with a telescope.
