Which is the largest moon, orbiting the planet Neptune?
Irregular moon Irregular moon In astronomy, an irregular moon, irregular satellite or irregular natural satellite is a natural satellite following a distant, inclined, and often eccentric and retrograde orbit. They have been captured by their parent planet, unlike regular satellites, which formed in orbit around them. As of July 2018, 125 irregular moons are known, orbiting all four of the outer planets (Jupiter, Saturn, Uranus and Neptune). The largest of each planet are Himalia of Jupiter, Phoebe of Saturn, Sycorax of Uranus, and Triton of Neptune. It is currently thought that the irregular satellites were captured from heliocentric orbits near their current
Neptune XIV Neptune XIV Neptune XIV, originally known as S/2004 N 1, is a small moon of Neptune, about in diameter, which orbits the planet in just under one Earth day. Its discovery on 1 July 2013 increased the number of Neptune's known satellites to fourteen. The moon is so dim that it was not observed when "Voyager 2" flew by in 1989. Mark Showalter of the SETI Institute found it by analyzing archived Neptune photographs the Hubble Space Telescope captured between 2004 and 2009. The moon was formally numbered Neptune XIV (14) on 25 September 2018 in Minor Planet Circular 111804.
