| 11. | But how close are the Solar System's other moons to their Roche limits?
|
| 12. | :That would be the Roche limit.
|
| 13. | Hence, using the data above, the Roche limits for these objects can be calculated.
|
| 14. | This corresponds to the Roche limit.
|
| 15. | A picture like this might put things into perspective and Roche limit is a relavant reference.
|
| 16. | The Roche limit sets the absolute restrictions to how big and how close the satellite can be.
|
| 17. | However, since it is not breaking up, it must still lie outside its rigid Roche limit.
|
| 18. | Therefore, these planets could have small moons close in, although not within their respective Roche limits.
|
| 19. | Objects only break up inside the Roche limit if there is nothing other than gravity holding them together.
|
| 20. | In particular tidal forces prevent the formation of bodies by gravity inside the Roche limit . "'
