Dynamical lifetime

{{one source |date=March 2024}} In statistical orbital mechanics, a body's '''dynamical lifetime''' refers to the mean time that a small body can be expected to remain in its current mean motion resonance. Classic examples are comets and asteroids which evolve from the 7:3 resonance to the 5:2 resonance with Jupiter's orbit with dynamical lifetimes of 1-100 Ma.<ref>{{cite book|title=Dynamics of Populations of Planetary Systems: Proceedings of the 197th Colloquium of the International Astronomical Union Held in Belgrade, Serbia and Montenegro August 31 - September 4, 2004 |editor1-first=Zoran |editor1-last=Knežević |editor2-first=Andrea |editor2-last=Milani |publisher=Cambridge University Press|year=2005|isbn=0-521-85203-X |chapter=Dynamical evolution of extrasolar planetary systems |first1=Ji-Lin |last1=Zhou |first2=Yi-Sui |last2=Sun |doi=10.1017/S1743921304008452|s2cid=23021391 }}</ref>
