Detailed explanation-1: -In the study of dynamical systems, an orbit is a collection of points related by time evolution. The points of the orbit will be a subset of the phase or state space of the dynamical system. If the dynamical system is a map, the orbit is a sequence and if the dynamical system is a flow, the orbit is a curve.

Detailed explanation-2: -In the case of an open orbit, the speed at any position of the orbit is at least the escape velocity for that position, in the case of a closed orbit, the speed is always less than the escape velocity.

Detailed explanation-3: -Earth and many other bodies, including asteroids, comets, and the other planets, move around the sun in curved paths called orbits. Gravity between the sun and Earth pulls Earth toward the sun, but Earth never falls into the sun. The moon orbits Earth rather than the sun because it is much closer to Earth.

Detailed explanation-4: -A periodic orbit corresponds to a special type of solution for a dynamical system, namely one which repeats itself in time. A dynamical system exhibiting a stable periodic orbit is often called an oscillator.
