en.wikipedia.org/wiki/Orbit

In physics, an orbit is the gravitationally curved trajectory of an object, such as the trajectory of a planet around a star or a natural satellite around a planet. .... The paths of all the star's satellites are elliptical orbits about that barycenter. .... The orbit of a planet around the Sun is an ellipse, with the Sun in one of the focal points ...

en.wikipedia.org/wiki/Horseshoe_orbit

A horseshoe orbit is a type of co-orbital motion of a small orbiting body relative to a larger orbiting body (such as Earth). The orbital period of the smaller body is very nearly the same as for the larger body, and its path appears to have a horseshoe shape as viewed from the larger ... Its orbit around the Sun still takes only slightly more than one Earth year.
