This dimension names the larger body that a celestial object orbits, such as a star, a planet or the galactic center. Wikipedia defines an orbit as "the curved trajectory of an object under the influence of an attracting force," the same relationship that ties a moon to its planet or a planet to its star. Browsing this way collects every object that circles the same parent body.
