Inside the Roche limit, tidal forces from the primary exceed the satellite's own gravity and pull it apart — the origin of planetary rings. The rigid-body limit is d = R·(2·ρ_primary/ρ_sat)^(1/3). Drag the moon inside the red ring to shred it.

Governing equation

d = R (2 \frac{ρ _{M}}{ρ _{m}})^{1/3} = 1 (2 \cdot 1.0)^{1/3} = 1.26 R

Reading this result: Outside the Roche limit: at 2.5 R the moon has a 98% margin above the 1.26 R threshold, so its own gravity holds it together.

About this simulation

The full Roche Limit tool models a meteor shower with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
