The shape of Triton from limb profiles

Limb profiles from Voyager 2 images of Triton show it to be an ellipsoid of axes 1354,6, 1352.8, and 1352.4 km (+/- 0.9 km). Topography on the limbs s uggests no large provinces such as "continents" with relief over a kilomete r. The shape solution is not accurate enough to constrain Triton's moments of inertia. The apparently relaxed shape is consistent with the youthful ge ologic features and supports interpretations that atmospheric distortion su ggested by occultation data is due to atmospheric phenomena rather than phy sical body distortions.
