Neptune VII

   Larissa ("LA ree suh") is the fifth of Neptune's known satellites:
        orbit:    73,600 km from Neptune
        diameter: 193 km (208 x 178)
        mass:     ?    
   Larissa was the mother by Poseidon (Neptune) of Pelasgus.

   Larissa was "officially" discovered in 1989 by Voyager 2 though it was observed in 1981 by Dave Tholen and colleagues using the stellar occultation method.

   Like Proteus, Larissa is irregular (non-spherical) in shape and appears to be heavily cratered.
