| Abstract: | The presence of central peak craters and the absence of central pit craters on Triton implies a surface rigidity similar to the Saturnian and Uranian satellites and stronger than that of the Jupiter satellites Ganymede and Callisto. Tectonically degraded terrain may exist at the antipode of the large impact structure on 1989N1. Dome craters on Triton may represent a form of solid state volcanism. |
