👉 In astronomy, "subtercelestial" refers to celestial bodies that are located below the planet Earth and beyond the orbit of the Moon. These celestial objects include planets like Jupiter, Saturn, Uranus, and Neptune, as well as dwarf planets such as Pluto and Eris. The term is used in conjunction with "astronomical subregions," which refer to the regions within a larger celestial body that are subject to the gravitational pull of stars and other celestial bodies.
