Why Planetary Rings Are Importanth2>
Planetary rings serve as natural laboratories for studying orbital mechanics, gravitational resonances, wave propagation, shepherding moons, and collisional physics. Saturn’s rings, in particular, are composed of 99.9% water ice and display thousands of ringlets, gaps, and density waves driven by moons like Prometheus and Pandora. Understanding ring dynamics helps us interpret exoplanet debris disks and the early evolution of planetary systems.p>
Purpose of This Calculatorh2>
This tool exists to make accurate ring physics accessible to everyone. You can:
- Determine if a moon can survive inside the Roche limitli>
- Calculate orbital periods and velocities at any radiusli>
- Locate major resonances (e.g., 2:1, 3:2) that create gapsli>
- Visualize ring density and brightness profilesli>
- Compare real ring systems with theoretical modelsli>

Scientific Foundationh2>
All calculations follow standard formulas:
- Roche limit (fluid)strong>: d = 2.44 Rₚ (ρₚ/ρₘ)¹ᐟ³li>
- Orbital periodstrong>: T = 2π √(r³/GM)li>
- Circular velocitystrong>: v = √(GM/r)li>
- Resonances located where orbital period ratios are simple fractions (2:1, 3:2, etc.)li>
ul>
These are the same equations used in peer-reviewed papers (e.g., Hedman & Nicholson 2016; Tiscareno et al. 2013).p>
Applications in Astronomyh2>
The calculator is ideal for:
- Modeling Cassini mission data for Saturnli>
- Studying narrow ring systems of Uranus & Neptune
-
- Exploring hypothetical rings around exoplanets
-
- Teaching gravitational dynamics in classrooms
-
