The lengthy reply is far more fascinating.
Gods within the skies
The very first planetary our bodies to be named have been these seen to people 1000’s of years in the past, lengthy earlier than the Worldwide Astronomical Union (IAU) obtained concerned.
Apart from Earth, the Moon, and the Solar, which got names within the earliest languages, the primary planets to be named have been these clearly seen within the night time sky with the bare eye: Mercury, Venus, Mars, Jupiter, and Saturn.

In 1781, when William Herschel found Uranus, he wished to call it after England’s King George III.
