Roche limit is minimum distance satellite can orbit before tidal forces exceed self-gravity, disrupting it into rings.

Stapsgewijze handleiding

  1. 1Input primary density, satellite density, and mass ratio
  2. 2Calculate rigid or fluid limit depending on satellite type
  3. 3Results show minimum stable orbital distance

Uitgewerkte voorbeelden

Invoer
Earth-Moon: Roche limit ~2.46 Earth radii (within Moon orbit)
Resultaat
Moon stable but gradually receding
Currently ~384,400 km

Veelgemaakte fouten om te vermijden

  • Confusing rigid and fluid Roche limits
  • Not accounting for density differences

Veelgestelde vragen

Are Saturn rings inside Roche limit?

Yes, explaining why rings exist instead of moon.
