Moon-Mars aspects

It is difficult to find two different planets than Mars and the Moon. They are two of the most important planets and both can significantly impact the trajectory of a birth chart or synastry.

To understand the dynamic of a relationship, we have to look at the planet that governs action and instincts, Mars. But to understand the emotional aspect and deepest desires, we must refer to the Moon and its placement in the synastry chart. 

Mars, the planet of war

Mars is the most masculine planet. It is all about the direction this planet chooses to channel its energy. This direction can be influenced by other placements in the chart but also by our personality. Knowing how the fiery energy of Mars impacts us and our relationships will help us take the right actions in the right direction.

This planet represents primal instincts, aggression, ambition, determination, and impulsiveness. It brings strength in ourselves and helps us use it to survive the most difficult situations. 

Being the rules of the fire sign Aries, Mars brings its fire to any chart, increasing the intensity in the aspect of the chart that it influences. Depending on how the energy of this planet is aspected, it can be both beneficial and malefic in a relationship. 

The Moon aspects

The most feminine planet, the sensitive Moon, rules the water sign Cancer. This is channeling the energy of our emotional needs, desires, and inner sense of security. The celestial body helps us identify and listen to our intuition as a protective mechanism.

The Moon wants us to be safe and unharmed, using all its spiritual vibrations to warn us about potential dangers threatening our sensitive hearts. 

As feminine energy, the Moon brings out the delicate and vulnerable side of us. However, it needs to ensure that the relationship is safe enough for this type of treasure. It speaks about what we might search for in a partner and what we need in our intimate relationships. 

A well-aspected strong Moon will give us the emotional intelligence to protect us from harmful connections. At the same time, a poor-aspected Moon will make it challenging to find a sense of security within a relationship.

The Moon will also impact how we react emotionally to tricky situations and our inner strength to move on after the most profound disappointments. 

Mars opposite Moon synastry 

The relationship’s longevity might be challenged when the Moon and Mars are in opposition, despite the strong attraction between the two partners. It can be challenging to look at this synastry placement from a positive perspective as most of its impacts on the relationship tend to be negative.

When they are in opposition, they tend to sabotage the positive sides and amplify the disadvantages. 

The illusion of a good connection will be present, at least at the beginning of the relationship. But as time goes by, the two partners might react intensely and impulsively toward each other. Mars individuals might trigger Moon people with their aggressive way of approaching situations.

In response, a Moon partner will overreact emotionally and manifest in dramatic arguments. The Moon person will also feel weak, or fragile, around the Mars person. This leads to low self-esteem and a lack of confidence in their intuition and abilities. 

Such a connection can still function long-term if mutual effort is invested. You want to identify the relationship’s problems and work on them before they get out of control. 

Emotional connection 

At an emotional level, this relationship could get overwhelming fast. The Moon is intense and wants to feel the same intensity echoed in the partner. But Mars responds with action more than emotional intensity, and the two partners approach their relationship very differently.

If the Moon is in the chart of the man and Mars is in the chart of the woman, this unbalance between the two might be smoother. But with Mars amplifying an already masculine energy and the Moon amplifying a feminine energy, there can be a real power imbalance.

Mars opposing Moon can also contour a fascinating relationship. During the good times, these two partners love to be around each other with all their intensity. The emotional bond is present, and they can enjoy a passionate relationship.

However, the expression of this emotional connection can bring emotional conflicts. They might not speak the same love language. 

Physical attraction and sexual relationship

The physical connection might be the only deep connection that functions enough to keep such a relationship going, despite all the discrepancies. The attraction is present for both partners and stays strong as time goes by.

The Mars person loves the emotional intensity of the Moon person, and it almost fuels their fire it. Simultaneously, the Moon person might see their Mars partner as a hero or a courageous individual and look up to them for that. 

A strong sexual attraction is also beneficial as long as there is a mutual curiosity to discover each other and experience new adventures together. The Moon also represents fertility. There is always a strong possibility of having children, even without planning to form a family.

The desires of the Mars person will, however, want to take the couple’s intimacy to new highs. They might not find the cooperation they need in their partner.

The needs of the Moon person are centered on the emotional and spiritual aspects of the bond. On the other end, the Mars person feels action and sex are a priority. These mismatched priorities can lead to a lot of tension.

Mental connection 

In other synastries, Mars and the Moon can usually motivate each other and create a common foundation of growth for both partners. However, when these two are opposites, the effects are quite different.

Power struggles and competition between these two partners might prevent them from working together. They would instead want to be better than their partner and struggle to reach the spotlight in the relationship.

The ambitious and aggressive Mars will not give up so easily. This can make the Moon person feel too emotional for such a conflict right in their personal life, where they aim to feel safe.

Teamwork is challenging and impossible unless there are other harmonious aspects in the synastry to balance this Mars-Moon opposition. 


The benefits of Moon opposition Mars are few; they are not the ones that will keep this bond together. But it is still essential to be aware of the positives in this synastry placement and make the most out of it to help the connection healthily withstand the test of time. 

Intense attraction 

Despite all the shortcomings, this relationship will be based on a lot of desire. The two partners will love to be with each other and explore different sides of their sexuality. Mars sets the tone regarding physical intimacy while the Moon channels the emotional intimacy.

This gives them a very intense experience together. Things seem to work in the bedroom, and they might even have high intimate compatibility. 

Great determination 

When used beneficially, the determination of the Mars person and the Moon person could help them build a strong bond. Hopefully one that can overcome the rest of the obstacles.

Mars doesn’t like to lose; if this is a relationship based on love, the Mars person will be determined to make it work. The Moon person will most likely respond with the same determination. The best outcome will be that both of them will work as a team to maintain their bond growing strong. 

Shared adventures 

Mars brings a high level of excitement in all aspects, and this is no exception. If the Moon person has an adventurous side, Mars will know how to bring the best out of it.

The experiences might be many and the lessons learned as well. This couple could grow together and individually through the experiences they share.

Having common hobbies and interests will also help significantly as they will find more pleasure in exploring their interests together. 


Mars opposing the Moon brings plenty of challenges, and it will take a lot of will to get through them.

Impulsive reactions 

Both Mars and the Moon work on impulses; the difference is only the root of those impulses. The Moon person tends to be emotionally impulsive, while the Mars person tends to be hasty in actions. The Moon person will struggle to add some stability to the relationship.

Their emotional reactions are often desperate tries to slow down the aggression that Mars brings. Reckless decisions could be taken in this couple, and the consequences will not be easy. 

The Mars person needs to take the time and listen to what the Moon partner feels. If they learn to communicate constructively, these two people could keep their impulsive instincts under control and avoid troublesome situations. 

Emotional arguments and dramas 

The arguments are rarely light with this synastry aspect. The Moon fuels each disagreement with intense emotions, and Mars can create an argument out of nothing. Senseless fights and heavy words might be frequent and damage the relationship entirely. 

Mars doesn’t react well to emotional conversations, and the Moon person could feel like they are talking to a wall. Their emotions will only amplify due to the desire to receive the attention and understanding they crave from their partner. 

The more emotionally attached these two people are to each other, the more intense their arguments will be. The Mars person might hurt the Moon person even without wanting that, and the arguments could often repeat throughout the relationship. 

Both partners need to develop a sense of patience so they can understand or at least accept each other. It is crucial to learn how to listen before voicing an opinion, as such a synastry placement is close to walking on eggshells. 

Ego driven battles 

Mars feeds the ego much more than the Moon does, but it also has the power to activate other people’s egos in a synastry. The Mars person could awaken the sense of ego and power in the Moon person, and they will both want to fight for their position.

The ego struggles can often damage the relationship because they will care more about being right than their bond.

When the Moon person feels controlled by the Mars person, they might react dramatically to express their disagreement and regain themselves. At the same time, the Mars person will have a hard time if they loose an argument or to allow their partner to call the shots. 

If they don’t tame their egos and learn to put the other person first so the connection can function, they might get lost in ego struggles. An emotional rollercoaster that doesn’t lead anywhere. 

Risk of being trapped in a toxic relationship

With the high fertility brought by the Moon and the sexual intensity brought by Mars, this couple has a high possibility of unwanted pregnancies. If this happens, one or both partners might feel trapped in a relationship that doesn’t make them happy.

Having a responsible intimate life will help them stay on top of this risk and only form a family when their bond is strong enough to sustain it. 

Final thoughts 

Mars opposite Moon is not an easy placement for a couple, but the two partners can still find ways to work around it. However, it takes a lot of emotional maturity and self-control to make such a relationship work in the long run.

If the love is mutual and strong, all the effort will be worth it in the end! It’s all about mutual understanding and compromise.
