Orbital stability

Orbital stability may refer to:

• The stability of orbits of planetary bodies
• Resonance between said orbits
• The closure of the orbit of a reductive group, in geometric invariant theory
• A stable electron configuration

In mathematical physics or theory of partial differential equations, the solitary wave solution of the form is said to be orbitally stable if any solution with the initial data sufficiently close to forever remains in a given small neighborhood of the trajectory of .
