Five tiny blue-colored rings have been discovered 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. At first, they thought that the rings might not be complete. This was proven wrong by "Voyager 2". 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.
