This dimension sorts celestial objects by their basic kind, such as a planet, star, galaxy or comet. Wikipedia notes that "asteroids, moons, planets, and stars are astronomical bodies," while looser structures such as "planetary systems, star clusters, nebulae, and galaxies" count as objects in the wider sense. Browsing by object type keeps similar kinds of objects grouped together.
