Does Neptune have rings? Yes, Neptune has several faint rings around it. There are three main rings which are very thin and dark. The rings are made up of small rocks and dust. Neptune's rings are not the same thickness all around. There are areas of the rings which are much thicker than other areas of the rings. These thicker parts are called ring arcs. Some of these ring arcs are also twisted. Because Neputune's rings are so dark and faint, they were not discovered until the 1980s.
