# Elliptical Orbit — AP Physics C Mechanics Definition

## Definition

An elliptical orbit refers to the path followed by an object (such as a planet or satellite) around another object under the influence of their mutual gravitational attraction. It is characterized by an elongated shape resembling an ellipse, with one focus occupied by the central body.
