Sun Opposite Mercury Synastry: Relationships and Friendships Explained

The Sun opposite Mercury is a difficult aspect in synastry. On the whole, it tends to be negative, but there can be positive points to it as well.

The Sun is complicated in synastry. On one hand, it brings energy and vitality to the relationship. On the other hand, it is where our ego and pride can sabotage our connection with other people.

Mercury is one of the most important planets when it comes to relationships. It governs our ability to communicate.

Good communication can save difficult relationships, and bad communication can destroy good ones. Mercury connections between people are one of the biggest indicators of whether a relationship can stand the test of time.

Oppositions are hard and difficult aspects. Yet, they play an important and often positive role in relationships because they can bring balance.

Sun Opposite Mercury in Synastry

The Sun opposite Mercury creates a specific type of communication problem in all types of relationships. That is that one person’s communication style challenges the other person’s ego.

The person whose Mercury is involved says the exact things in the exact ways that are the most likely to trigger defensiveness in the other.

This makes it hard for the person whose Sun is involved to listen to what the other has to say.

The positive side to this is that, if they can get beyond this problem, it creates opportunities for each of them to grow. Whether the two will be able to get beyond this problem will in large part depend on whether there are more harmonious aspects between them.

This aspect becomes even more tricky in that Mercury and Venus are never very far from the Sun in any individual’s birth chart. This means that there are likely to be other oppositions between the Sun, Mercury, and Venus between the two charts.

There are many sign combinations that will change the meaning of this aspect.

Aries and Libra; Leo and Aquarius

Aries and Leo give the Sun strength, and their opposite signs, Libra and Aquarius, weaken it. If either of these sign combinations is involved, the issues will be primarily connected to ego and pride.

When one person’s Sun is in either Libra and Aquarius, and the other’s Mercury is in either Aries or Leo, the aspect will be easier to manage. It will be easier for the Sun in Libra or Aquarius to listen to what the other has to say.

One the other hand, when one person’s Sun is in either Aries or Leo, this aspect will be even more difficult. The Sun’s pride will be powerful, and Mercury will not have the patience or inclination to try to break through that pride.

Gemini and Sagittarius; Virgo and Pisces

In these signs, the issues will directly involve communication. Mercury is strong in Gemini and Virgo and is weak in Sagittarius and Pisces.

If one person’s Mercury is in either Sagittarius or Pisces, they will have trouble with communication in general, but the other person will give them confidence. This will improve this aspect and strengthen the relationship.

If one person has Mercury in either Gemini or Virgo, however, they will have excellent communication skills. While this is great for them on an individual level, it makes them less patient with the person whose Sun is in the opposite sign of Sagittarius or Pisces.

They will tend to blame the other for communication problems rather than try to solve them. This will make this aspect more difficult and create more problems in the relationship.

House Position

Oppositions represent polarities. The house positions of the Sun and Mercury in each other’s charts will determine the primary area of life that they struggle with together.

Man’s Sun Opposite Woman’s Venus Relationship

The Sun opposite Mercury is a stressful aspect in a romantic relationship, particularly when it is a man’s Sun opposite a woman’s Mercury.

All of the difficult stereotypes of the “battle of the sexes” can potentially come into play if they are not careful. He will have a lot of trouble listening to her and respecting her intelligence. She, in turn, will be tempted to stop trying.

Whether a relationship with this aspect can last will depend a lot on the other aspects that are between them. It will be particularly important to see if there are other aspects between the Sun, Mercury, and Venus in their charts.

The good news is that if there are other more harmonious aspects between them, and if they are both willing to work on their relationship, this aspect could become a strength rather than a weakness.

They have the ability to balance and complement each other, which could help both of them to grow as people.

Woman’s Sun Opposite Man’s Mercury Relationship

This aspect is usually not quite as difficult when it is the woman’s Sun that is opposite a man’s Mercury.

It will be hard for her to listen to him, and she may fail to appreciate his intelligence. Social pressures with respect to gender roles will tend to mitigate this problem, however.

Other people will likely encourage her to work on being more receptive to him, and he is likely to have more confidence when it comes to standing his ground and speaking his mind.

On the other hand, she could become even more stubborn, thinking that it is an issue of gender roles rather than her own ego and pride.

Just as when the genders are reversed, if they can work through their issues, this aspect can help them to balance and complement each other.

Sun Opposite Mercury in Friendship

This aspect will tend to create distance when it comes to friendships. It could prevent them from becoming too close.

This can be unfortunate because they have the potential for being very good for each other. The person whose Mercury is involved could be a great advisor if the person whose Sun is involved can set aside their ego and listen.

They may not agree with each other, but they can give each other excellent perspective.

Just as in a romantic relationship, it is important to look at the other aspects between the two.

Opposites by Zodiac Sign in Synastry

If a person’s Sun is the opposite sign from another person’s Mercury, the influence of this aspect will be present.

This aspect is at full strength if the planets are within twelve degrees of a perfect opposition. The closer the planets are, the more powerful the aspect will be.

With the Sun opposite Mercury, the closer the aspect is, the more direct the conflict will be.

If the planets are within twelve degrees of an exact opposition from the wrong signs, the aspect will be present in a changed form. In this case, the aspect will be much worse as the two come into conflict without the benefit of being able to balance each other.

Conclusion

The Sun opposite Mercury in synastry creates difficulty in communication. One person’s ego is in conflict with the communication style of another.

The problems created by this aspect can be managed, however, especially if the two have more harmonious aspects between them.

If the two do learn to communicate with each other, this aspect can be beneficial to both of them.
