This is somewhat difficult to judge. I don't think astrologers would find the current glyph for U+29EC unacceptable, but the glyph typically being used has the circle smaller than Mars, Venus, and either of the two Earth symbols. Sometimes, an oval is used instead of a circle. However, some styles for astrology symbols have very large circles.

I've found the proposals (from 2000), but many symbols there have no explained use, including U+29EC.
If the members of this mailing list think a proposal including a separate Eris symbol is acceptable, I will include it in my proposal.
Along with, perhaps, some additional symbols...
