Neptune has six known rings. Voyager 2's observations confirmed that these unusual rings are not uniform but have four thick regions (clumps of dust) called arcs. The rings are thought to be relatively young and short-lived. Neptune has 13 known moons, six of which were discovered by Voyager 2.
Why was slavery introduced to the English colonies? Slavery was introduced to the English colonies because people were  in need of labor to develop the lands.
