The distribution of the known moons over the planets is shown in the following table, which also displays for each planet the last year of the discovery of a moon (per 2006-05-25).
This table shows the moons that are on average the furthest from or the closest to the center of their planet, measured in units of 1000 km.
The orbits of moons that are far enough away from their planet are influenced by the gravity of the Sun.

 Tide Summary
The relative distance of the Moon from the Earth also affects tide heights: When the Moon is at perigee the range increases, and when it is at apogee the range is reduced.
The Moon's gravity differential field at the surface of the earth is known as the Tide Generating Force.
Because the Moon's tidal forces drive the oceans with a period of about 12.42 hours (half of the Moon's synodic period of rotation), which is considerably less than the natural period of the oceans, complex resonance phenomena take place.

Each of the moons of Neptune is named after the nymphs and minor sea deities of Greek and Roman myth, in keeping with Neptune's (and Poseidon's) title in mythology as the lord of the sea.
Also, much like Earth's moon, Triton is tidally "locked" with Neptune, meaning that the time it takes to make one rotation is the same as the time it takes to orbit the surface of Neptune.
Most of these moons are only a few dozen to a few hundred kilometers in diameter, leading scientists to believe that they may have simply been objects captured in Neptune's orbit.
