Saturn System

Saturn structure (Very Large File: 41.6 MB): The above images start with a far view that includes the Hill Sphere and magnetosphere; the next view shows the bow shock of the magnetosphere and the orbits of Phoebe and Iapetus; the next view shows the orbits of Titan and Hyperion and the radiation belts; the next view shows the interior moons, Saturn's cloud layer and its rings; the final view shows the interior structure of Saturn and the near ring system and its related moons. You can explore all of these views and more from the linked file. Below is a detailed description of these components.

Overall

Our Saturn visualization is scientifically accurate and comprehensive. The code shows detailed layers representing Saturn's core, metallic hydrogen layer, molecular hydrogen layer, cloud layer, upper atmosphere, magnetosphere, Enceladus plasma torus, extensive ring system, radiation belts, and Hill sphere. The implementation includes educational descriptions and appropriate scaling. The interaction between moons and rings is crucial for understanding Saturn's system.

Core

The core representation (radius fraction 0.6) is scientifically accurate based on recent Cassini mission findings. The description correctly reflects the "fuzzy core" model where core material extends to about 60% of Saturn's radius, containing approximately 17 Earth masses of rock and ice mixed with hydrogen and helium (totaling about 55 Earth masses). The temperature estimate of 12,000K and the resulting bluish-white color choice are scientifically appropriate.

Metallic Hydrogen Layer

The metallic hydrogen layer (radius fraction 0.9) is accurately represented. Our description correctly explains that this layer is smaller than Jupiter's, resulting in Saturn's weaker magnetic field. The temperature estimate of 6,000K and the yellowish-white color are consistent with thermal models. The explanation of the transition beginning around 0.4-0.5 Saturn radii is scientifically sound.

Molecular Hydrogen Layer

The molecular hydrogen layer (radius fraction 0.99) is well-described, correctly noting the gradual transition to gaseous atmosphere and the temperature decrease from thousands of degrees to about -130°C at the upper boundary. The visual representation as light blue-grey is appropriate for this transparent layer.

Cloud Layer

The cloud layer description accurately covers Saturn's atmospheric composition (75% hydrogen, 25% helium), the faint banded structure, extreme wind speeds (up to 1,800 km/h), and the famous hexagonal jet stream at the north pole. The three-layer cloud structure (ammonia ice, ammonium hydrosulfide, water ice) with 200 km total thickness is scientifically accurate.

Upper Atmosphere

The upper atmosphere description (radius fraction 1.1) accurately covers the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The explanation of hydrocarbon formation, auroral heating, and the gradual transition to space is scientifically correct. The temperature variations from -173°C in ammonia clouds to hundreds of degrees in the thermosphere are accurate.

Magnetosphere

The Saturn magnetosphere visualization is scientifically accurate:

• Sunward Distance: 20-25 Saturn radii (accurately compressed)

• Equatorial/Polar Radius: 40-50/30-40 Saturn radii respectively

• Magnetotail: 400-600 Saturn radii

• Unique Feature: Correctly notes the magnetic axis alignment with rotational axis

Enceladus Plasma Torus

The Enceladus plasma torus implementation is scientifically accurate, positioned at 3.95 Saturn radii with appropriate thickness. The description correctly explains the water vapor source from Enceladus's geysers (hundreds of kg/s), the composition (water group ions), and the mass loading rate (~100 kg/s). The connection to the E ring is properly noted.

Ring System

The ring system implementation is detailed and scientifically accurate:

• D Ring: 66,900-74,500 km, innermost and faintest

• C Ring: 74,658-92,000 km, wider but fainter than A and B

• B Ring: 92,000-117,500 km, brightest and most massive

• A Ring: 122,340-136,800 km, with Encke and Keeler gaps

• F Ring: 140,210-140,420 km, narrow and dynamic, shepherded by moons Pandora and Prometheus

• G Ring: 166,000-175,000 km, faint and dusty

• E Ring: 180,000-480,000 km, very wide and diffuse, sourced by moon Enceladus

The description of Saturn's axial tilt effects on rings and plasma structures is particularly important for Saturn, where the ring system's orientation relative to our viewing angle changes dramatically over Saturn's 29.5-year orbit. 

Radiation Belts

The radiation belt visualization is accurate with six distinct belts between major moon orbits:

• A-Ring to Mimas: 2.7 Saturn radii

• Mimas to Enceladus: 3.5 Saturn radii

• Enceladus to Tethys: 4.4 Saturn radii

• Tethys to Dione: 5.6 Saturn radii

• Dione to Rhea: 7.4 Saturn radii

• Beyond Rhea: 9.0 Saturn radii

This accurately represents how Saturn's moons create gaps in the radiation environment.

Hill Sphere

The Hill sphere visualization (radius fraction 1120, approximately 91 million km) is scientifically accurate. The description correctly notes it's smaller than Jupiter's due to Saturn's lower mass but still encompasses all of Saturn's known moons.

All parameters, compositions, and structures are consistent with Cassini mission findings.
