The Satellites of Neptune

Neptune has thirteen known moons (see also Miner and Wessen, 2002 [231]). The largest satellite is Triton (Fig. 4.23) which is on retrograde orbit around Neptune. Only six moons have diameters larger than 100 km. 

Some important parameters for satellites of Neptune larger than about 100 km are given in Table 4.4.
