A trajectory or flight path is the path that a moving object follows through space as a function of time.[1] The object might be a projectile or a satellite. For example, it can be an orbitthe 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.
