Caption:
Voyager 2 took this image of Neptune's irregularly-shaped satellite 1989N1 from a range of 870,000 kilometers (540,000 miles). The resolution is 8 kilometers (5 miles) per pixel. The satellite has an average radius of about 200 kilometers (120 miles) and is uniformly dark with an albedo of about 6 percent. The irregular shape suggests that 1989N1 has been cold and rigid throughout its history and subject to significant impact cratering.
Background Info:
The Voyager Mission is conducted by JPL for NASA's Office of Space Science and Applications.
