Neptune
There are five rings around the planet. They are not as well known as the rings of Saturn. The rings were discovered by a team led by Edward Guinan in 1968. Then, in the mid-1980s astronomers thought that the rings might not be complete.  Stellar occultations were found that rarely showed an extra "blink" just before or after the planet moved in front of the star. However, Voyager 2 showed that they were complete. The planetary rings of Neptune have a weird "clumpy" arrangement. Scientists think that it may be because of the gravitational contact with small moons that orbit near them. Pictures showed that the ring system had several faint rings. The farthest ring, Adams, has five arcs now named Courage, Liberté, Egalité 1, Egalité 2 and Fraternité (Courage, Liberty, Equality, and Fraternity).
