In astronomy, Hénon is well known for his contributions to stellar dynamics. In the late 1960s and early 1970s he made important contributions on the dynamical evolution of star clusters, in particular globular clusters. He developed a numerical technique using Monte Carlo methods to follow the dynamical evolution of a spherical star cluster much faster than the so-called n-body methods.
In mathematics, he is well known for the Hénon map, a simple discrete dynamical system that exhibits chaotic behavior.
He published a two-volume work on the restricted three-body problem.
In 1978 he was awarded the Prix Jean Ricard.
