An elliptical orbit is the path that an object takes as it moves around another object in an oval shape. This type of orbit is common in space, where celestial bodies like planets and moons travel around stars and other planets. The shape of the orbit is defined by two points called foci, with one focus being the center of the object being orbited, such as a star. In an elliptical orbit, the distance between the orbiting object and the central object changes over time. This means that the orbiting object moves faster when it is closer to the central object and slower when it is farther away. This behavior is described by Kepler's laws of planetary motion, which explain how planets like Earth and Mars travel around the Sun.
