In ancient times, humans had only known offive planets besides Earth: Mars, Venus, Mercury, Jupiter, and Saturn. It wasn't until 1781 when William Herchel looked into the sky and saw a strange "star" in the sky that we knew of more planets. As for the name, some had been suggested, like Minerva (the Roman goddess of wisdom), Juno (queen of the Roman gods), and even Neptune (the Roman god of the ocean), which would eventually be the name of the next planet discovered! There was also an attempt to name it Georgium Sidus, which is Latin for "George's Star". The George in question was King George III, who was the monarch of England at the time. However, one name became the victor above all the rest, and that was Uranus, the Greek god of the sky. This is the first time a planet had been named after a Greek god rather than a Roman one.
