Knowing which Moon signs are compatible can help you determine how well you might get along with someone when it comes to emotional interactions. Keep in mind, there's more to this type of compatibility than meets the eye; you'll need to consider how the Moon sign relates to the Sun sign and other factors.
Moon Sign Meaning Compatibility Simplified
Many astrologers consider the Moon the most important "planet" in relationships. The Moon represents your emotions. Your Moon sign is how you instinctively react to outer events and what you need to feel comfortable and secure. Which means it's difficult to be with someone who isn't in sync with your Moon. Much like Sun sign compatibility, when your Moon is in an easy aspect to one or more of your partner's planets, you feel comfortable, safe and secure with one another. Below is a handy chart that helps to further explain.

The Astrological Aspects
Aspects are usually measured by mathematical angles, but skipping the geometry and just using the astrological signs, there are the five major aspects astrologers look at in chart comparison.
The five major aspects:
- Conjunct (same sign); Blending (easy)
- Sextile (2 signs apart); Flowing (easy)
- Square (3 signs apart); Dynamic (difficult)
- Trine (4 signs apart) Flowing (easy)
- Opposite (6 signs apart); Dynamic (difficult)
Sun and Moon in Astrological Compatibility
The Moon and the Sun are natural companions in astrology, so it's a very good sign if they are in an easy aspect to one another. When they are at ease with one another, the Moon person relies on and trusts the Sun person's wisdom, spirit, and personal style, while the Sun person depends on the emotional support of the Moon person. If the Sun and Moon are in a difficult aspect, the Moon person is likely to find that the Sun person becomes overbearing and insensitive, while the Sun person finds the Moon person too temperamental, dependent, and emotional.
Moon and Moon in Astrological Compatibility
When two Moons are in an easy aspect, the individuals are comfortable with each other due to their similar tastes and emotional sensibilities. If two Moons are in a more difficult aspect, the individuals are not in sync and certain habits and idiosyncrasies each will make the other uncomfortable.
Moon and Mercury in Astrological Compatibility
When the Moon and the planet Mercury connect, communication is stimulated. In an easy aspect, a couple can enjoy long, intimate conversations, confide in each other, and share our inner feelings and thoughts. However, with the difficult aspects, the Moon person is likely to find the Mercury person too nitpicky and too often detached, while the Mercury person can be irritated by the Moon person's sensitivity and mood swings.
Venus and Moon in Astrological Compatibility
When the planet Venus and the Moon are in easy access, you genuinely like each other and share a natural affection and a desire for partnership. When in a difficult relationship there will be frustrating times when one individual's values will conflict with the other's emotional needs.
Mars and Moon in Astrological Compatibility
When the planet Mars and the Moon are in aspect to one another, there's a strong attraction that's both physical and emotional. If the aspect is easy, the Moon person nurtures and has a soothing and calming effect on the Mars person, while the Mars person encourages the Moon person to be brave and confident. However, the relationship can still be tumultuous and a difficult aspect will only make this relationship more tumultuous.
Jupiter and Moon in Astrological Compatibility
When the planet Jupiter and the Moon are in an easy aspect to one another, there is a great capacity for openness and goodwill between partners as well as honest and candid communication. The more difficult aspects can lead toward excess, emotions getting out of control and unrealistic expectations.
Saturn and Moon in Astrological Compatibility
When the Moon and the planet Saturn are in an easy aspect, the Saturn person is supportive of the Moon person, who finds the Saturn person a reliable and steady partner. However, even with easy aspects, the couple will have their ups and downs, while with the more difficult aspects there could be a feeling of being trapped. In either case, the connection runs deep and it's not a frivolous relationship.
Uranus and Moon in Astrological Compatibility
When the Moon and the planet Uranus are connected, there's electric chemistry that's exciting and fascinating, but there will be an erratic quality to the relationship. If the aspect is easy, the couple will delight that their relationship doesn't fall into a rut and enjoy doing things a little differently. With the more difficult aspects, the relationship can be emotionally unsettling to the Moon person and too conservative and domestic for the Uranus person.
Neptune and Moon in Astrological Compatibility
The Moon in aspect to the planet Neptune can be magic or befuddling. When there are easy aspects between the Moon and Neptune you are gentle and caring with one another. You can even anticipate each other's moods and responses. When the aspect is difficult, there will be misunderstandings, avoidance or neglectful behaviors as well as a tendency to be dishonest with one another.
Pluto and Moon in Astrological Compatibility
Regardless of the aspect, a couple with the Moon and the planet Pluto connected have a strong emotional attachment to one another and are likely to have a very passionate relationship. With the easy aspects, they will easily share many secrets and intimate details about their lives. With the more difficult aspects, the emotional tension can be so intense, fear of loss can be generated, which in turn can give rise to jealousy, control or possessiveness.
Shining a Light on Potential Problems
This is just a very basic and small sampling of what Moon sign compatibility looks like. A professional astrologer compares the Suns, Moons, Ascendants, and the other planets as well as all the aspects and house placements in both birth charts. However, there's no such thing as perfect astrological compatibility, so, even if there's no interaction between the Moon and other planets in a couple's astrological synastry it's not the kiss of death to the relationship. Astrology can't predict who you'll fall in love with, why, or if it will be long lasting, but it can shine a light on potential problems.
