Astronomicals are objects in space that are not habitable, and not a world of any kind. This category includes comets, nebula, and similar objects. Moons fall into this category only if they are too small to be habitable, of a particular nature to prevent them from being habitable (e.g., made of energy), or have insufficient data to classify them as an independent world. Luna (the earth's moon) would be considered a World, as would the larger moons of Jupiter.
