Known Space -- Sol -- Neptune -- | Nereid |
Nereid is the eighth of Neptune's satellites. It is so far from Neptune that it requires 360 days to make one orbit. The moon's surface reflects about 14 percent of the sunlight that strikes it, making it somewhat more reflective than Earth's Moon, and more than twice as reflective as Proteus. Nereid's orbit is the most eccentric in the solar system.
