Neptune: Roman God of the Sea

Once Neptune was recognized as a planet and not just a star, it triggered an earthly battle among scientists. Who really discovered it? And what should it be named? Francois Arago, Leverrier’s teacher (and this website’s namesake), wanted recognition for his French protégé, and even suggested that the planet be named after Le Verrier.

It was agreed that Adams’s highly coincidental work could not be ignored, so both he and Leverrier are credited with the discovery of Neptune. However, Arago and Leverrier did succeed in winning some points for the French; two of Neptune’s rings are named after them. The planet itself was named after the Roman god of the sea, inspired by its color and watery surface. Close-up photos of Neptune were taken by the Voyager 2 spacecraft in 1989.
