   Implications for Planetary Bodies
   For celestial bodies, gravitational equilibrium is usually discussed in terms of hydrostatic equilibrium. A body is in hydrostatic equilibrium when its self-gravity is precisely balanced by internal pressure gradients, preventing it from collapsing further or expanding. This state is a necessary condition for a body to be classified as a planet or dwarf planet.
   However, the mood of the planet also plays a subtle, measurable role. Observations suggest that planetary bodies experiencing extended periods of in…
