Juno in the horoscope gives a good indication of the kind of marriage partner that we need and will get. Not the partner we think we want (those are ruled by Venus and Mars), but the one we need and actually wind up with.
Juno is the "Divine Consort", goddess of marriage, revered for her loyalty and fidelity. Juno was known to the Greeks as Hera, from the roots he-era, "the earth", also translated as "lady", the feminine form of "hero".
Juno represents both the need for relationship and the refusal to accept inequality within the context of a relationship. She represents the struggle to balance the need for intimacy with the opposing need for freedom
