| 21. | The table below gives each satellite's closest approach in its orbit divided by its own Roche limit.
|
| 22. | The Roche limit is usually considered in relation to natural bodies that are held together by their own gravity.
|
| 23. | The Roche limit implies that small planets with orbits of a few hours are likely made mostly of iron.
|
| 24. | If its density is similar to Amalthea's then its orbit would actually lie within the fluid Roche limit.
|
| 25. | A weaker satellite, such as a comet, could be broken up when it passes within its Roche limit.
|
| 26. | Additionally, it was within the Roche limit, meaning it might disintegrate due to the Sun's gravity.
|
| 27. | The moon's material strength and resistence to tensile stress would keep it intact inside it's Roche limit.
|
| 28. | :That depends on the fluidity of the body, the time it spends and the distance inside the Roche limit.
|
| 29. | Once the orbit of the Moon closes to a distance of, it will cross the Earth's Roche limit.
|
| 30. | Indeed, almost all known planetary rings are located within their Roche limit, Saturn's Phoebe ring being notable exceptions.
