Trivia: Which planet name was not derived from Greek or Roman mythology?
Earth
Mercury
Uranus
Pluto
The correct answer is Earth
So why is this answer correct? : Earth is the only planet in the solar system not named after a Greek or Roman god. The word “earth” has been around since at least the 15th century, from the Old English term “eorpe,” meaning “ground, soil, dirt, dry land; country, district,” and “the material world, the abode of man,” just as we use it today. “Eorpe” came from the Proto-Germanic term “erþ ō,” which stems from the Proto-Indo-European root “er-,” meaning “ground.”
