The only planet in our solar system not named after a god is Earth. All the rest are named after ancient Roman deities.
Mercury was the god of commerce and travel and was Jupiter’s messenger.
Venus was the goddess of love and the mother of Cupid.
Earth comes from the old Germanic word for ground or soil.
Mars was the god of war.
Jupiter was king of the gods.
Saturn was a god of agriculture and Jupiter’s father.
Uranus was a sky god and Jupiter’s grandfather.
Neptune was the god of the ocean.
Pluto – no longer considered a planet – was the god of death and the underworld.
I heard some scientist said that perhaps if we could go beyond our Solar system, beyond the Milky Way, even beyond other distant galaxies, post the end of the observable universe, we’ll find that there’s more, a lot more, that our universe is not alone. There may be other universe. In fact, there might be new ones being born all the time. We may actually live in an expanding see of multiplying universes: a “multiverse”.
