P-34698 These Voyager 2 images of satellite 1989N2 at a resolution of 4.2 kilometers (2.6 miles) per pixel reveals it to be an irregularly shaped, dark object. The satellite appears to have several craters 30 to 50 kilometers (18.5 to 31 miles) across. The irregular outline suggests that this moon has remained cold and rigid throughout much of its history. It is about 210 by 190 kilometers (130 by 118 miles), about half the size of 1989N1. It has a low albedo surface reflecting about 5 percent of the incident light.
