Definition
Uranus is an icy giant planet characterized by a fluid envelope rich in volatiles. Its organization is based on superposed layers with varying properties, and its markedly tilted rotational axis influences energy distribution and atmospheric regimes.
Internal structure
The internal structure exhibits a succession of regions where composition, density and fluid states change progressively. External layers contain light gases and cold fluids, while deep zones are dominated by dense volatile mixtures. A central core, solid or partially fluid, acts as the foundational structure.
Atmosphere and fluid envelopes
The atmosphere consists of cold, stratified regions showing circulations, zones and vortex systems. Internal transitions define energy distribution and influence atmospheric motions and exchanges between deep and superficial layers.
Tilt and distinct dynamics
The planet’s strongly tilted axis changes the exposure of atmospheric regions, creating pronounced seasonal variations in the organization of flows. This configuration affects interactions between rotation, internal gradients and atmospheric phenomena.
Orbital interactions
Uranus interacts with a set of satellites and fine structures close to its orbital plane. These objects respond to the gravitational conditions of the central body, contributing to a coherent environment where internal phenomena and orbits intertwine.
