A late 18th century guide to astronomy listing the most recent observations. Included in the list of known planets is a then-recent discovery, a planet named "Hershel" - what is today known as Uranus. Discovered in 1781 by the German polymath, Sir Frederick William Herschel, the planet was first known as "The Georgian Star", for Britain's King George III. Due to the King's lack of popularity in France, that country used the name "Hershel".
