Ganymede: Ganymede is both the largest moon of Jupiter, our Solar System's planetary behemoth, as well as the largest moon in our entire Solar system. Observations of Ganymede by the HST in 2015 suggested the existence of a subsurface saline ocean. This is because patterns in auroral belts and rocking of the magnetic field hinted at the presence of an ocean. It is estimated to be approximately 100 kilometers deep with a surface situated below a crust of 150 kilometers.
Venus Square to Mars. Venus, the goddess of love, harmony and beauty is fighting with her lover Mars over their very different point of views. Venus is in Scorpio and wants deep commitment and honesty. Mars is in playful Leo and likes to play, seduce and tempt the goddess. Men are from Mars and women are from Venus and they are often very different if their perspectives, needs and desires. I always thought that book from John Gray was genius in playing on the deep archetypes we all have in us.
As discussed the Moon is a 'feeling' planet. Therefore having Moon in a Water element (Cancer, Scorpio or Pisces) will intensify the 'feeling' nature. Therefore anyone or anything that allows the nurturing quality to be used or expressed will assist you in feeling secure and at home with yourself. On a negative note this type of Moon could be clinging, possessive and controlling in a nurturing way.
