For example, keeping the sphere centered - once it gets out of place, the areas closer to sun will be attracted even more, while those far out will be attracted even less. Positive feedback will complete the destruction. | |

Simply some vibration that happens to be in a normal vibration mode of the sphere (thus causing resonance) will destroy it. | |
