Jupiter (F6)
Jupiter is a massive body dominated by a deep fluid envelope structured into dynamic layers governed by vast circulations. Its internal transitions organize a coherent system marked by powerful fields.
Icy giant planet without rings (F5)
An icy giant planet without rings exhibits a cold, layered fluid envelope shaped by internal gradients, lacking any solid orbital structure. Gradual transitions determine its dynamic organization.
Icy giant planet with rings (F4)
An icy giant planet surrounded by rings features a cold fluid envelope associated with an orbital structure composed of solid particles. The whole system is shaped by internal gradients and gravitational interactions.
Gas giant planet with massive rings (F3)
A gas giant planet surrounded by a vast ring system, where a deep fluid envelope coexists with an orbital structure made of solid particles and dispersed materials.
Gas giant planet without rings (F2)
A gas giant planet composed mainly of gases, lacking a ring system, where a deep fluid envelope and gradual internal transitions shape the structure and organize atmospheric motions.
Mars (F1)
Mars is a rocky body shaped by a cold surface, scattered sediments and an extremely thin atmosphere, where ice, dust, rocks and atmospheric circulation interact to form a contrasting environment.
Terrestrial planet with a thin and dry atmosphere (E9)
A terrestrial planet with a thin atmosphere possesses a highly reduced and dry gaseous envelope, where the rocky surface interacts weakly with limited energy flows, forming an unprotected yet stable environment.
Earth (E8)
Earth is a rocky body structured into solid, fluid and gaseous layers, where the surface, waters, atmosphere and dynamic fields interact to form a coherent geophysical system.
Venus (E7)
Venus is a terrestrial planet with a dense carbon-dioxide layer and clouds of sulfuric acid, creating an extremely energetic environment dominated by volcanic processes.
Terrestrial planet with thick and toxic atmosphere (E6)
Rocky planet enveloped by a dense and poisonous atmosphere, where heat and pressure create an extreme environment dominated by opaque and corrosive clouds.
Mercury (E5)
The smallest and closest planet to the Sun, Mercury orbits rapidly and shows a cratered surface with extreme temperature variations from -173°C to 427°C.
Rocky terrestrial planet without atmosphere (E4)
A rocky planet without an atmosphere is a solid body directly exposed to space, with no gas layer to protect or moderate surface conditions.
Sun (E3)
As the central star and energetic engine, the Sun shapes the rhythms, orbital motions, and living conditions of surrounding worlds. It embodies the living balance of a constantly evolving system.
Telluris (E2)
Telluris are rocky bodies of the dwarf planet class, without a permanent atmosphere, with a solid structure dominated by silicates, metals, and sometimes ice, preserving traits of the early protoplanetary disk.
Netherion (E1)
Netherion-class planets are small icy bodies located in the outer regions of stellar systems, covered with volatile ices and exhibiting complex, unstable orbits.
Thermocryas (D9)
Thermocryas are a theoretical class of moderately warm ice giants, intermediate between Borealis and Pyrogiants in orbital irradiance. Warmer than classical ice giants yet below widespread ionization, they exhibit altered chemistry and dynamic weather.
Aquilides (D8)
Aquilides are icy giant planets with a high fraction of volatiles, dense internal layers, a hydrogen-helium atmosphere, methane absorption, and strong winds at very low temperatures.
Pyrogiants (D7)
Pyrogiants are massive gas planets orbiting very close to their star, characterized by extreme temperatures, ionized atmospheres, metallic vapors, fast winds, and large thermal contrasts.
Gigantides (D6)
Gigantides are giant gas planets without a defined solid surface, composed mostly of hydrogen and helium, with layered atmospheres, high wind speeds, frequent rings, and numerous satellites.
