### Freebase(5.00 / 1 vote)Rate this definition:

1. Trajectory

A trajectory is the path that a moving object follows through space as a function of time. The object might be a projectile or a satellite, for example. It thus includes the meaning of orbit—the path of a planet, an asteroid or a comet as it travels around a central mass. A trajectory can be described mathematically either by the geometry of the path, or as the position of the object over time. In control theory a trajectory is a time-ordered set of states of a dynamical system. In discrete mathematics, a trajectory is a sequence of values calculated by the iterated application of a mapping to an element of its source.
