This baby moon will most likely be destroyed by tidal forces in the future. Ocean tides most of us know, but Earth tides are something fewer think of though it is the same forces that come into play. In the case of Phobos the tidal forces will eventually cause enough stress on the poor moon that it will disintegrate. Relax, the Earth tides are not that powerful. No stress! :-)
