How many moons does Neptune have?
As of July 2013, we know of fourteen moons orbiting Neptune. The largest, Triton, was discovered only 17 days after Neptune itself was found in 1846 and it would be over a hundred years before any others were first seen. Triton is one of the larger moons in the Solar System with a diameter of 2700km, and orbits backwards around Neptune. The most recently discovered moon, by contrast, is less than 20km across, and is known as S/2004 S1, until the IAU votes on a proper name for it.
