So the moral of this comic is that Randall doesn't classify cometary tails as celestial bodies?

:Are they ''structures'', though? (Either of the two tails, from any given comet.) Insofar as sunspots, arguably as structural as anything 'on' the Sun, in terms of plasma/magnetic-field interactions, but tails are particulates/ions set adrift from the solid nucleus that don't really form a body, ''per se'', and practically are uncordinated individual ejecta in a way that (arguably, loosely) the formation of sunspot material is not. But IANAAstrophysicist, and I imagine the definition boundary is even fuzzier than a comet's (''or'' a star's) corona, amongst those experts who study the various phenomena with great intensity!
