An elliptical orbit is when an astronomical object travels around its primary body in an oval-shaped path. Some synonyms for elliptical orbit include eccentric orbit, oval orbit, oblong orbit, and elongated orbit. An eccentric orbit refers to an orbit that is not circular but has a definite shape and elongation. Oval orbit refers to a path with a rounded shape, while oblong orbit looks like an oval but is more elongated than a circular orbit. Lastly, an elongated orbit refers to a path with an irregular shape that is stretched out more than a circular orbit. These synonyms are useful for astronomers when studying celestial bodies and their movements.
