While the general answer seems to be "yes", there remains some ambiguity on the point of exactly what the thing should be called.
One of the major factors in that determination may have to do with how big the object is. or how far it is from another celestial body. However, since celestial bodies themselves can be extremely large, an error equal to the radius of the body could be problematic.
So, this raises the question:
Are in-game distances from stars/planets/etc. given as a distance from the center, or the surface, of an object?
Secondarily, it would also probably be useful to know if there's a way to accurately measure the size and/or mass of in-game celestial bodies.
