Mother of God 

Christianity considers Mary to be the Mother of God since Mary is considered as the mother of Jesus Christ.

The constellation Virgo, the Virgin, is identified with Mary, the Mother of God.  Mary is just one of the many Virgins who have given birth to God.

If the Mother of God gave birth to God then it seems logical that the Mother of God existed before the entity called God and therefore the Mother of God must be, by default, the real God, who had to exist before God (Jesus Christ) could have been born..  However we are told that Mary, the Mother of God according to Christianity, was born from a human mother, thus meaning that the Mother of the Mother of God had to exist long before God.  Very confusing and not logical at all!

The Mother of God seems to also be considered the Queen of Heaven.

Mary, the Mother of God, is said to have Ascended into Heaven on 15 August, which is when the star Spica set at the time of the birth of Jesus Christ.  The Birth of Mary, the Mother of God, is said to have been on 08 September, which is when the corn star Spica is said to have reappeared on the other side of the Sun.

Christianity considers Mary to have been taken into Heaven.  Perhaps Mary appears in the Heavens as the Constellation Virgo.  Perhaps, but not likely, Virgo was not there until Mary was taken into the Heavens by God.
