This stylized depiction of the ITN is designed to show its (often convoluted) path through the Solar System . The green ribbon represents one path from among the many that are mathematically possible along the surface of the darker green bounding tube. Locations where the ribbon changes direction abruptly represent trajectory changes at Lagrange points , while constricted areas represent locations where objects linger in temporary orbit around a point before continuing on The interplanetary transport network (ITN) [ 1 ] is a collection of gravitationally determined pathways through the Solar System that require very little energy for an object to follow.
