Mercury - Mercury is one of the five brightest planets glittering in the sky and came to the notice of the Romans. Mercury, the god of travel and commerce. This is the Roman equivalent of the ancient Greek god Hermes, the messenger of the gods.
Venus - Venus is the second planet in the solar system and our closest celestial neighbor. This led it to be named after the Roman goddess of love and beauty, Venus.
Earth - Earth is the largest terrestrial planet and the fifth-largest planet in the solar system. The name “Earth” is not a Roman or Greek god but rather a millennia-old English/German word that simply translates to “Ground”.
Mars - Mars is the fourth planet from the sun and the second-smallest planet in the solar system. The planet was eventually named Mars, after the Roman god of war, for the same reasons.
Jupiter - Jupiter is the largest planet in the solar system. Due to its stature, Jupiter is considered the King of all planets. Thus, it is rightly named after the king of all the ancient Roman gods.
Saturn - Saturn is the sixth and second-largest planet in the solar system. It is named after the Roman god of agriculture and wealth.
Uranus - The first ice giant, Uranus is the seventh planet from the sun. As for why it was renamed Uranus, Johann Bode decided to stick with the Roman-Greek tradition of naming planets and named it after the Greek god of the heavens or sky, due to its sky-blue color.
Neptune - The second ice giant consecutively placed after Uranus, Neptune is the other blue planet. Galle intended to name it after its predictor, Le Verrier, but the International Astronomical Community disagreed and decided to name it after the Roman god of the sea.
