Have you ever wondered Why our planet is called EARTH? As far as I can recall in all of my science subjects from Elementary up to college did not even tackle this. Well, I thought about it but we don't really have any subject relating to "Etymologies" and etymology does not really fit in a science discussion since it deals more with history and facts. So EARTH is just earth, everyone just accepted it.

Earth by the way is also the largest of the Solar System's four terrestrial planets. It is sometimes referred to as the World, the Blue Planet, or even Planet Earth or by its Latin name, Terra. The name Earth originates from the 8th century Anglo-Saxon word erda, which means ground or soil. In Old English the word became eorthe, then erthe in Middle English.

Earth was first used as the name of the sphere around the 1400s. It is the only planet whose name in English is not derived from Greco-Roman mythology. By that, EARTH stands out compared to the planets in our solar system wherein they are named after mythological Gods.

Now we know EARTH!
