CICLOPS: Cassini Imaging Central Laboratory for OPerationS

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.

The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
