Hyperbolic trajectory

trajectory of any object around a central body with more than enough speed to escape the central object's gravitational pull

In astrodynamics, a hyperbolic trajectory (which is also an escape trajectory) refers to an object (such as an asteroid) which follows a path similar to a hyperbola around a central object. This motion follows Kepler's Laws. A hyperbolic trajectory occurs when the eccentricity of its orbit is greater than 1.

Other types of motion in astronomy include circular orbit, elliptical orbit, and parabolic trajectory.
