Neso

Neso, also known as Neptune XIII, is the outermost known natural satellite of Neptune. It's a retrograde irregular moon discovered by Matthew J. Holman, Brett J. Gladman, et al. on 14 August 2002.
Neso is about ~60 km in diameter based on an assumed albedo.
Given the similar orbital elements with Psamathe, it was suggested that both irregular satellites could have been a fragment piece of a much bigger moon in the past.
Neso's furthest point is much further than the distance between the Sun and Mercury.
