Is it possible for a planet to wobble rather than have a fixed axial tilt? Probably not without a moon or three that are massive enough to pull it about (and that would be rather massive, IIRC), though if the material composition of the moon(s) isn't stated it's vaguely possible they're made of something terrifyingly dense and thus would actually be massive enough for such an effect. . .
Which makes me wonder, do we know what causes axial tilt in the first place?
