Neptune and Its Satellites


Neptune is shown here in an image from Voyager 2 taken in 1989 from 16,000,000 km away. The Great Dark Spot is visible, a circular storm about 13,000 km long and 6,600 km wide. (Credit: NASA, JPL)
Despina is seen here in a Voyager 2 image taken in August 1989. Despina is 150 km across. (Credit: NASA, JPL)
Larissa is seen here in a Voyager 2 image taken 24 August 1989 from a distance of 2,450,000 km. Larissa is 210 km across. (Credit: NASA, JPL)
Proteus is shown in this Voyager 2 image taken 25 August 1989 from 144,000 km away. Proteus is 440 km across. (Credit: NASA, JPL)
Triton is seen here in a photomosaic of Voyager 2 images taken 25 August 1989. Triton's surface is a mixture of nitrogen and water ices. The dark streaks are material deposited downwind from nitrogen geysers erupting into Triton's thin nitrogen atmosphere. Several such geysers were observed erupting during Voyager 2's flyby. The light coloring towards the right in the image may be a layer of frost on the surface. (Credit: NASA, JPL)
Nereid is seen here in a Voyager 2 image taken in August 1989 from a distance of 4,700,000 km. Nereid is 340 km across and orbits Neptune in a distant, highly eccentric orbit. (Credit: NASA, JPL)
