List of Neptune's moons
The following table contains the most important data of all 14 known natural satellites of Neptune .
The most important dates of the moons of Neptune
Legend for the following table
| No. | Final number of the moon |
| Surname | Proper name |
| preliminary reference | Provisional designation |
| a | Major semi-axis in km |
| e | Numerical eccentricity |
| i | Orbit inclination in degrees |
| T | Orbital period in days |
| D. | (Mean) diameter in km |
| M. | Mass in kg |
| discovered | first reliable proof |
| <10 km |
| 10 to 30 km |
| 30 to 100 km |
| 101 to 300 km |
| 301 to 1000 km |
| > 1000 km |
An orbit inclination of more than 90 ° means that the satellite is orbiting Neptune retrograde . As a rule, moons move prograd , i.e. H. in the same direction of rotation around the planet as the planet rotates around its own axis.

diagram
The diagram opposite shows the horizontal orbit half-axes (abscesses, in million km) of the Neptune moons and their vertical inclination (ordinate, in degrees): The circle sizes do not show the relative lunar radii to the orbital elements. The horizontal lines represent the area between perihelion and aphelion of the respective lunar orbit.
