I'd say quite compatible, although there are many other factors regarding astrology charts. Aquarius sun and Libra sun are both air signs. You both are ruled by intellect. You like to go out and have interests you share. The Aquarius person is a nonconformist but Taurus moon people don't like change and are very grounded, so that's a bit challenging. Taurus moon people are loyal, sexy and loving. They don't like to argue or make waves unless you upset them.
Libra is a social creature and one who likes to be surrounded by beauty. This is a charming person who has a lot of friends. Libras like nice things because they like to show them off, but a Taurus moon likes nice things because they work hard and believe they deserve comfort in life.
A Virgo Moon and Taurus moon are both earth signs, and the moon rules your emotional makeup. Both of you are caring and will be devoted to a relationship if it goes farther. You are both hard workers who are serious about security in life, but on the outside, you both come off as more sociable than you are. A Virgo moon is a perfectionist who may be a tad critical but also has high standards for themselves.
