When the Sun in one chart forms an aspect to another person’s Sun.
Sun conjunct Sun in synastry:
Your overall characteristics and energy levels are very similar. You strongly identify with each other and are very much alike in important ways. It is easy for you to be together because you do not have to explain yourselves to one another. An innate appreciation and understanding of one another’s essence exists between you, and this is vitalizing and ego-affirming for both of you. However, you share the same flaws and weaknesses as well as the positive qualities, and you may find it difficult to be with someone who so clearly exhibits the very things you like least about yourself. The more you accept yourself, the more beneficial and delightful your relationship with one another is.
Sun opposition Sun in synastry:
Opposites attract! Although the two of you have many basic differences in your personalities, you are, nevertheless, attracted to each other and intrigued by each other. This is not a lukewarm relationship! It can easily lean towards a love-hate relationship: you love and respect each other when you are able to complement each other, and you hate each other when you fail to understand and appreciate your differences. When disagreements arise, the argument is between your egos. Beware of appearing haughty, judgmental, or self-righteous with each other when really the argument is about differences in basic temperaments. When “ego wars” occur between the two of you, remember that your partner is never going to be what they weren’t born to be. Appreciate your basic differences, as you have much potential to complement each other. It is up to the two of you to develop mutual appreciation for your differences rather than antagonize each other.
Sun square Sun in synastry:
Your relationship is dynamic and energizing. You challenge each other to grow and develop, but unfortunately the process tends to be abrasive and frustrating. The differences in your personalities, if not understood and handled properly, can lead to mutual frustration. Your life goals may often be at odds with one another, and this fact can deplete both of your senses of vitality. There can be distinct “ego wars” between you, especially if you are around each other often. Competitiveness can be a real problem. Although it may be pleasantly challenging at times, and especially at the beginning of your relationship, the need to defend one’s basic personality can be draining. Your relationship can easily become a love-hate one.
Sun trine Sun in synastry:
You energize each other! Although your goals don’t always jive, you nevertheless feel supported by your partner. In a general sense, you endorse one another. This is a very positive and strengthening aspect in your relationship. Each of you affirms and confirms the other’s purpose. Together, you feel you are going somewhere. Your basic aims and approach to life are in harmony, and the mutual respect you feel forms the basis of an excellent friendship or partnership. You feel understood, appreciated, recognized, and affirmed by one another. You stimulate, vitalize, motivate, and believe in each other in an overall sense. Of course, there are challenges in your relationship, but this particular aspect strengthens your overall belief in one another.
Sun sextile Sun in synastry:
This aspect is a very supportive one in any chart comparison. It helps iron out other differences. There is a great deal of compatibility between you, for you understand and are in harmony with one another’s basic needs, aims, and approach to life. You build up, encourage, and affirm one another’s worth and self-esteem, and you find one another’s company very comfortable and natural. This is a mutually beneficial relationship.
General notes about Sun-Sun contacts in synastry:
With the hard aspects, there is generally a strong reaction to one another, whether it’s attraction or dislike. There can be ego conflicts and competitiveness. Care should be taken not to try to knock each other down with blows to the ego. I have seen friendships and other relationships with Sun square Sun contacts suddenly fall apart over what appears to be (from the outside looking in) a simple disagreement about different temperaments. The key to handling these relationships is to avoid becoming haughty and self-righteous with one another. Statements that begin with “you should…” must be avoided, because they only serve to make the partner defensive. Acceptance and understanding needs to be worked on in order for the relationship to survive. When the aspects are flowing, there is a strong sense of compatibility. The individuals tend to boost each other’s energy levels, or, at the very least, allow each other to function efficiently without draining energy from each other. This is mainly due to the fact that there is little need to explain oneself to each other. They can also be extremely proud of one another! Whether this is expressed through liberal compliments between the two, or boasting about one’s partner to friends and family, or both, there exists a mutual respect and pride in the relationship.
