* Roman God: Neptune is named after the Roman god of the sea, just like the planet Uranus is named after the Greek god of the sky.
* Other Cultures: Different cultures have their own names for celestial bodies. While not a "name" for Neptune, it's interesting to consider how other cultures viewed the planet.
* Historical Names: Before its discovery, Neptune was sometimes referred to as "Le Verrier's Planet" or "Adams's Planet" after the astronomers who predicted its existence.
So, while Neptune doesn't have a "nickname" like a person might, it's important to remember its connection to the Roman god of the sea and how other cultures might have viewed it.
