<sturnclaw> Pretty sure that's because the moon's mass is the smallest
            expressible number in 32.32 fixed-point [08:33:16]
<sturnclaw> that's an unfortunate issue but more a side-effect of how we
            generate bodies [08:33:37]
<sturnclaw> Nothing I can really do about it at the moment - I think the
            massive icon is a completely different issue from the moon being
            generated with a low mass [08:34:09]
<sturnclaw> ...or rather it's a display issue rather than something directly
            stemming from the moon's lack of mass [08:34:27]
