Sun Sextile The synastry of Mercury is one of the most critical aspects in a composite chart. All Sun-Mercury aspects speak to how a couple communicates and understands each other. They bring out each partner’s core identity and how they interact with each other. When Mercury is involved, these synastry aspects are rational rather than emotional.
If you have a sextile between the Sun and Mercury in your synastry chart, you’ll want to fully understand the implications of this aspect and get the most out of it!


The energies of the Sun and Mercury
As the only star in our horoscope, the Sun gives us our authenticity. It is the vital force that drives us every day. It also speaks of our ego and conscious self. As ruler of Leo, the Sun tends to make us proud, confident, energetic, generous and sometimes arrogant. This star wants everyone to enjoy the light, but if you get too close, you will burn! Its placement in our chart reveals our zodiac sign and sun sign. The house of the SSunin, a birth chart, shows where our sense of ego, creativity and vitality are most likely to manifest.
Mercury is one of our planets, along with Mars, Venus, the sun and the moon. It is also the planet closest to the Sun and the ruler of Gemini and Virgo, two profound psychological signs. Mercury represents intellect, communication, logical and analytical skills. It shows how we process information and our skills to express our thoughts.

The intellectual potential of this relationship encourages a constructive exchange of ideas. The two partners have similar communication styles, creating great synergy. This effective communication allows them to develop new ways of thinking, even with different opinions. The Mercury person is always interested in lively debates, and the Sun person brings ideas that can lead to stimulating conversations.

Challenges of the Sun sextile Mercury synastry
The challenges in the SSunsextile Mercury synastry also depend on the planets or points in the two birth charts. Each placement is essential when looking at a composite diagram. For example, a Sun or Mercury in Aries can manifest itself more aggressively than a Sun or Mercury in Pisces.


Risk of overthinking
Mercury aspects always carry the risk of overthinking. The Mercury person can create tension with their overanalyzing mind, which the Sun person can find stressful. This risk is even greater in the Sun-conjunct Mercury synastry, but we can also find it in a Sun-Mercury sextile.
The Sun person must learn when to avoid Mercury going down a rabbit hole. And if it’s done with diplomacy and a caring attitude, the Mercury person will be receptive. The Sun person sometimes feels trapped by Mercury’s over-analytical nature, which can lead to unnecessary disagreements.
Emotional detachment
Even though the intellectual connection in this relationship is so strong, the sextile between Mercury and the Sun does not shine over the emotional bond in the most intense way. Both partners are attached and there is significant magnetism between them, but there can also be moments of emotional detachment.
The Mercury person should try to connect more deeply with their Sun partner. Sometimes love cannot be rationalized and they both have to allow themselves to fully feel their emotions.
Intellectual control
With Mercury’s sextile sun synastry, one person often wants to control the other, at least intellectually. This type of attitude can cause conflict that damages the relationship over time. The Sun person feels like he should be the leader in this union because of his potentially high ego. However, a healthy and harmonious relationship is based on something other than leadership and cooperation. One person’s desire to be in control is often unwarranted and even insulting.
