== Other cases of tidal acceleration == Most natural satellites of the planets undergo tidal acceleration to some degree (usually small), except for the two classes of tidally decelerated bodies. In most cases, however, the effect is small enough that even after billions of years most satellites will not actually be lost. The effect is probably most pronounced for Mars's second moon [[Deimos (moon)|Deimos]], which may become an Earth-crossing asteroid after it leaks out of Mars's grip.<ref>{{Cite journal |last1=Wiegert |first1=P. |last2=Galiazzo |first2=M.A. |date=August 2017 |title=Meteorites from Phobos and Deimos at Earth? |url=https://doi.org/10.1016/j.pss.2017.05.001 |journal=Planetary and Space Science |volume=142 |pages=48β52 |doi=10.1016/j.pss.2017.05.001 |issn=0032-0633|arxiv=1705.02260 |bibcode=2017P&SS..142...48W }}</ref> The effect also arises between different components in a [[binary star]].<ref>{{cite journal|last = Zahn|first = J.-P.|title = Tidal Friction in Close Binary Stars|journal = Astron.

The gravitational interactions within such systems can induce tidal forces, leading to fascinating dynamics between the stars or their orbiting bodies, influencing their evolution and behavior over cosmic timescales.
