Orbits are periodic or quasi-periodic trajectories, usually around a central celestial body like the Earth or the Sun.
For some arrival trajectories, low thrust propulsion is sufficient to achieve orbit insertion.
The angle relative to the equator and maximum altitude of these orbits are constrained by the rocket and launch site used.
The key difference between this kind of maneuver and powered trans-planetary orbit insertion is the significantly lesser change in velocity required to raise or circularize an existing planetary orbit, versus canceling out the considerable velocity of interplanetary cruise.
Although current orbit insertion maneuvers require precisely timed burns of conventional chemical rockets, some headway has been made towards the use of alternative means of stabilizing orbits, such as ion thrusters or plasma propulsion engines to achieve the same result using less fuel over a longer period of time.
