An orbit with the shape of a geometrical ellipse. All orbits are elliptical or hyperbolic, with the Sun occupying one focus.

an oval shaped orbit, the shape of which is caused by the gravitational interaction of to two or more revolving bodies.

An elliptical orbit is an orbit that traces out an ellipse as the orbiter rotates around another body (which is located at one focus of the ellipse).

Those orbits in which the satellite path describes an ellipse with the Earth at one focus.

An orbit where the satellite moves in a big ellipse (a shape like a flattened circle). A satellite in an elliptical orbit is sometimes close to the object it is orbiting and sometimes far away from it. A satellite in an elliptical orbit, especially a highly eccentric one, will move faster when it is close to the planet and slower when it is far away. An elliptical orbit can be useful to a communications satellite.
