chemical rocket

A type of rocketA fluid-dynamics concept that says as low-velocity gases pass into the converging part of a nozzleA type of rocket system that heats a propellant by passing it through a sustained electric arc, then ejects the energized gas through a nozzle.

circular orbit

A circular orbitA circular orbitA circular orbit has no perigee. In this case, we have no argument of perigee, or true anomaly, because both use perigee as a reference. More has no perigee. In this case, we have no argument of perigeeFor the fifth orbital element, we measure the angle along the orbital path between the ascending node and perigee and call it the argument of perigee. We always measure this angle in the direction of spacecraft motion. More, or true anomalyThe angle along the orbital path from perigee to the spacecraft's position vector.
