The invention discloses a planet low-energy orbit capture method based on a balance point and a periodic orbit, and relates to an orbit capture method, and belongs to the technical field of aerospace. The method uses characteristics of a balance point, a periodic orbit, and invariant manifold in a sun-plant-detector three-body system to realize capture of a detector by a planet. The method comprises: firstly, applying first engine driving at height of a pericenter which is relatively low relative to the planet, to enter a stable manifold in the three-body system, and sliding to the periodic orbit without power along the manifold, using the orbit as a parking orbit; then using an unstable manifold of the periodic orbit to get close to the planet, selecting an unstable manifold whose pericenter height is the same with that of a target orbit, and applying second engine driving when reaching the pericenter, to realize planet capture. Speed increment required by the method is low, flexibility is high, and the method is suitable for orbit capture of different planets. By using the characteristic of the periodic orbit, the planet can be observed in a capture process, so as to increase data of planet observation in a detection task.
