Photograph of one of Neptunes moons, known as 1989N1, taken as the spacecraft approached Neptune on 25 August, 1989. The moon, seen here half- illuminated, has an average radius of some 200 km. It is dark grey in colour and hints of crater-like forms and linear grooves can be discerned. The graininess of the image is caused by the short exposure necessary to photograph the speeding moon. The photograph was taken from a distance of 146,000 km and has a surface resolution of about 2.7 km.
