I firmly believe that Divine Providence is at work in all things that affect the world on a global scale. The naming of the planets would be such a thing. Without meaning to do so all the modern planets were assigned appropriate names for their later discovered astrological meanings and I feel confident that Eris and Ceres and the rest are in the same situation. Of course investigation and verification must be used to discover exactly how one should translate things from Mythology to Astrology (Neptune to Illusion/Obligation makes sense though it isn't directly understood). Eris as Chaos would be the first thing that comes to mind but it could also be Order and Harmony in certain aspects or Confusion or Misdirection or Deception or Frustration or Depression or Destruction or Order or something even more remote... how to narrow down the meaning and possible interpretations will definitely take a lot of work from a dedicated astrologer.
