Abstract
Four-planet system stability is intermediate of three- and five-planet system stability and are primarily effected by first and second order mean motion resonances. A stability phase shifting mechanism is also explored based on initial longitudes.

Outland is a doctoral student at the University of Colorado Boulder, Smead Department of Aerospace Engineering Sciences. His research is in differential game theory, safe multi-agent systems, and computational astrodynamics, with a focus on algorithms that are tractable enough to run onboard while providing formal guarantees.
