S/2004 N 1
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.[4] 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.[5]
Composite o Hubble Space Telescope images frae 2009 shawin Neptune, S/2004 N 1, an some o Neptune's rings an ither inner muins. The brichtness o the muins relative tae Neptune is greatly enhanced. | |
