walking orbit

Quick Reference

An orbit that drifts slowly in relationship to the surrounding fixed inertial space. This is a helpful occurrence for a spacecraft studying a planet's surface. A walking orbit around a body in space is caused by gravitational influences of other bodies, such as a moon or the Sun. It may also be caused by a planet that is not a perfect sphere. These factors can be configured into a spacecraft's trajectory in order to create a walking orbit.
