S/2004 N 1 is a smaa muin o Neptune, aboot 18 km (11 mi) in diameter, which orbits the planet in just unner ane Yird day. Its discovery on 1 Julie 2013 increased Neptune's retinue o kent satellites tae fowerteen. The muin is so dim that it wis nae observed when Voyager 2 flew bi in 1989. Mark Showalter o the SETI Institute foond it bi analyzing archived Neptune photographs the Hubble Space Telescope captured atween 2004 an 2009.

The designation "S/2004 N 1" is provisional; "2004" refers tae the year the data wis first acquired, nae the year o discovery.
