If and when astronomers name an asteroid or dwarf planet after Discordia she will become part of the family tree of Latin/Roman astrology.To understand how confusing life becomes when some astrologers mix up Greeks and Romans – imagine if we used Greek icons like the asteroid 69230 Hermes instead of (or in addition to) Mercury.
The Romans took Athena and turned her into Minerva, who is the daughter of Jupiter. She is actually the forerunner of Minerva.
Sedna is not in the Latin family tree of astrology – she is a symbol from a completely different culture – the Inuit people of the Arctic regions of Greenland, Canada and Alaska.
