    The "Georgian Planet" as engraved on the top plate refers the planet Uranus which was first observed by William Herschel on March 13th 1781a although he initially recorded it as a comet.
    The object was later universally accepted as a new planet and by 1783, Herschel himself acknowledged this fact to Royal Society president Joseph Banks "By the observation of the most eminent Astronomers in Europe it appears that the new star, which I had the honour of pointing out to them in March 1781, is a Primary Planet of our Solar System in recognition of his achievement King George III gave Herschel an annual stipend of £200 on the condition that he move to Windsor so that the Royal Family could have a chance to look through his telescopes.
    The Astronomer Royal, Nevil Maskelyne asked Herschel to "do the astronomical world the faver (sic) to give a name to your planet, which is entirely your own, [and] which we are so much obliged to you for the discovery of". In response to Maskelyne's request, Herschel decided to name the object Georgium Sidus (George's Star), or the "Georgian Planet" in honour of his new patron, King George III.
