Definition
Neptune is an icy giant planet whose organization is based on a fluid envelope rich in volatiles. Its environment consists of superposed layers with gradual variations in composition, density and state.
Internal structure
The interior contains successive regions where pressures, temperatures and fluid mixtures evolve progressively. Outer zones contain light gases, while deeper layers are dominated by compressed fluids and dense volatile mixtures. A central core, solid or partially fluid, serves as the organizational foundation.
Atmosphere and fluid envelopes
The atmosphere is marked by zones, rapid circulations and vortex structures. The deep envelopes show gradual transitions that influence the distribution of internal energy and the visible dynamics of the upper layers.
Dynamic activity
Neptune exhibits atmospheric phenomena organized by rapid rotation, deep gradients and internal interactions. The resulting dynamic structures lead to variations in the organization of flows and motions.
Orbital interactions
The planet interacts with satellites and structural objects within its orbital vicinity. These objects respond to the gravitational and dynamic conditions of the system, contributing to a coherent environment where internal processes and orbital organization intertwine.
