What specific physical state allows a massive KBO to earn the classification of a dwarf planet?
Answer
The object must exert enough gravity to pull itself into a nearly round shape due to hydrostatic equilibrium.
The distinction between smaller debris scattered throughout the Kuiper Belt and the larger worlds is based on mass and gravitational influence. Specifically, objects qualifying as dwarf planets are massive enough that their own gravity dominates their structure, forcing them into a state of hydrostatic equilibrium. This process results in the body assuming a nearly round or spherical shape, a clear visual indicator separating them from the smaller, irregularly shaped minor bodies populating the rest of the belt.
