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