Sun Trine Mercury in Synastry

By itself, the Sun trine Mercury indicates a high degree of compatibility between two people. It will make other positive aspects better, and it will lessen problems from difficult aspects.

This aspect will help two people communicate. It will give them the sense that they have a lot in common and that they can talk to each other about anything.

Furthermore, they can talk about difficult things while still protecting each other’s pride.

While the basic meaning of this aspect is consistent, there are a lot of variations depending on the signs involved.

Fire Signs (Aries, Leo, and Sagittarius)

This aspect is at its best if it occurs between the signs of Aries and Leo. The Sun rules Leo and is exalted in Aries. The person whose Sun is involved will tend to be the dominant of the two, regardless of whether their Sun is in Aries or Leo.

Even so, they will enjoy lively and enthusiastic conversations, which can sometimes turn into debates. No matter how much it looks like they are fighting to those on the outside, they will be having the time of their lives.

The situation is a little trickier if one person has the Sun in Sagittarius. This can produce a one-sided relationship in which that person will have a hard time listening to the other. This will be the case whether the other’s Mercury is in Aries or Leo.

Earth Signs (Taurus, Virgo, and Capricorn)

The Sun trine Mercury is also improved if one person has the Sun in Virgo. That person will be especially receptive to the other, regardless of whether their Mercury is in Taurus or Capricorn.

Those are the only combinations between the Earth Signs that change the meaning of this aspect in a significant way.

Air Signs (Gemini, Libra, and Aquarius)

Mercury rules Gemini, but is content in all three of the Air Signs. On the other hand, both Libra and Aquarius have trouble with the Sun.

If one person has Mercury is in Gemini, this will create a more positive version of this aspect.

If one person has Mercury in either Libra or Aquarius, however, this will create a one-sided version. The person whose Sun is involved will like the other person a great deal, but these feelings may not be reciprocated.

Water Signs (Cancer, Scorpio, and Pisces)

If one of the people involved has the Sun in Pisces, this will lessen the positive influence of this aspect a great deal. This person will be less receptive to the other, whether their Mercury is in Cancer or Scorpio.

All other combinations will be regular versions of this aspect.

House Position

In addition to the signs involved, it is also important to consider the houses that this aspect impacts in both of their individual birth charts.
