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 . "'
