Larissa

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 a daughter of Pelasgus.

   Harold Reitsma is now usually credited with the discovery of Larissa by ground-based stellar occultation observations. The first (and so far only) images of it were obtained by Voyager 2.

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