Roche limit is minimum distance satellite can orbit before tidal forces exceed self-gravity, disrupting it into rings.
دليل خطوة بخطوة
- 1Input primary density, satellite density, and mass ratio
- 2Calculate rigid or fluid limit depending on satellite type
- 3Results show minimum stable orbital distance

Earth-Moon: Roche limit ~2.46 Earth radii (within Moon orbit)
النتيجة
Moon stable but gradually receding
Currently ~384,400 km
أخطاء شائعة يجب تجنبها
- ✕Confusing rigid and fluid Roche limits
- ✕Not accounting for density differences
أسئلة شائعة
Are Saturn rings inside Roche limit?
Yes, explaining why rings exist instead of moon.
