Bill,
Methinks we are getting into the realms of semantics here!

By nature of the word, a spheroid is oblate. If it was a true sphere it would not be oblate. Large bodies that have a relatively fast axial rotation must become oblate and hence spheriodal. It would be interesting to find out the axial rotational rate of 2003 UB313. The spherical nature of an object does, to my way of thinking, impact on its status of planethood but you cannot take that factor by itself as per my previous post.
