Arcs in the Adams ring (left to right: Fraternité, Égalité, Liberté), plus the Le Verrier ring on the inside. The outer Adams ring, with an orbital radius of about 63,930 km, [4] is the best studied of Neptune's rings. [4] It is named after John Couch Adams, who predicted the position of Neptune independently of Le Verrier. [22]

The three main rings are the narrow Adams Ring, 63,000 km from the centre of Neptune, the Le Verrier Ring, at 53,000 km, and the broader, fainter Galle Ring, at 42,000 km. A faint outward extension to the Le Verrier Ring has been named Lassell; it is bounded at its outer edge by the Arago Ring at 57,000 km. [169]
The next moon, Galatea, orbits just inside the most prominent of Neptune's rings, the Adams ring. [21] This ring is very narrow, with a width not exceeding 50 km, [22] and has five embedded bright arcs. [21] The gravity of Galatea helps confine the ring particles within a limited region in the radial direction, maintaining the narrow ring.

The Royal Society awarded Le Verrier the Copley medal in 1846 for his achievement, without mention of Adams, but Adams's academic reputation at Cambridge, and in society, was assured. [3] As the facts became known, some British astronomers pushed the view that the two astronomers had independently solved the problem of Neptune, and ascribed ...
The James Webb Space Telescope has captured its first image of Neptune, and it's the best view of the planet's rings in over 30 years.
