Juno was the third asteroid to be discovered, in 1804, and is named for the Roman queen of the gods, the goddess of marriage and protector of wives.
Astrologically Juno is about committed partnership: what someone needs from a long-term relationship, how they understand loyalty, and how power and equality are shared between two people. It is concerned with the agreement as much as the romance, with what each person is promising and whether it feels fair.
Its sign and house describe the kind of partnership that feels like a real commitment, and its aspects show where trust, jealousy or the balance of power tend to be tested.
