Moon conjunct Mercury in synastry is an excellent aspect. By itself it will confer compatibility, unless there are a great many difficult aspects between the two.
The Moon has a very big role in astrology. It governs everything about our day-to-day lives and plays a huge role when it comes to communication.
Mercury’s role when it comes to communication is well-known. The Moon’s role is less commonly known.
The Moon is the fastest moving planet. For this reason, it traditionally governed messages and messengers.
The Moon also governs memory, which makes a difference as to whether a person is able to “forgive and forget” after a conflict.
A conjunction occurs when two planets are in the same place in the zodiac. In synastry, it shows places in which two people are alike. It is a neutral aspect, meaning that it can be either positive or negative depending on the planets involved.
Moon Conjunct Mercury Synastry
In synastry, the Moon conjunct Mercury will facilitate excellent communication between them. This is because the two primary planets governing communication are together in the zodiac.
Two people with this aspect between them will understand each other on a deep, intuitive level. Often they are able to communicate without speaking a word.
This aspect is not one that generates instant chemistry, however. The impact is much slower and comes from a place of calm.
Even so, Moon conjunct Mercury will hold two people together for a long time. Even if there are difficult aspects between them, they will be able to work through them.
There are a number of special sign combinations for this aspect which will either strengthen or weaken its positive effects.
Signs Where the Moon is Strong
The Moon rules Cancer and is exalted in Taurus. When this aspect occurs in either of these signs, the person whose Moon is involved will be a source of strength for the other.
They will be able to understand the other as few others can. Cancer and Taurus are both rather quiet signs, and Mercury in these signs tends not to talk very much.
This makes it all the more important that there are many things that the other does not need to be told to understand.
Signs Where Mercury is Strong
Mercury rules Gemini and Virgo. Mercury is also exalted in Virgo. When this conjunction falls in these signs, the two like to talk…a lot.
This aspect is enhanced in both of these signs, but it is at its best in Virgo. Not only is Mercury stronger in this sign, but it is a night sign, which means that the Moon is more comfortable there as well.
Signs Where the Moon is Weak
The Moon is uncomfortable in both Scorpio and Capricorn, and Mercury does not have any special dignities in either of these signs.
This aspect is still positive in these signs, but it is much weaker than it would otherwise be.
The person whose Moon is involved will have trouble expressing their thoughts and feelings, and the person whose Mercury is involved may not have the patience or inclination to help.
Signs Where Mercury is Weak
Sagittarius and Pisces are difficult signs for Mercury. Natives with these placements can struggle to communicate clearly.
When this aspect occurs in Sagittarius, its long-term benefits are greatly reduced. This is because neither of them will be inclined to stay and work on their communication.
This aspect is only slightly weakened in Pisces. Pisces is a night sign, and the Moon has some level of comfort in all of the night signs.
This means that the person whose Moon is involved can be a source of strength and clarity to the other, if the other allows it.
House Position
This aspect will highlight a specific house in each person’s chart. This will influence the interpretation of this aspect.

The person whose Mercury is involved will help the other articulate and work through their thoughts and emotions. The person whose Moon is involved will see things on an intuitive level that the other person may have missed.
How to Tell if the Moon is Conjunct Mercury in Synastry
If one person’s Moon is in the same sign as the other’s Mercury, this aspect will be present to a certain extent.
The closer the aspect is by degree, the stronger and more positive it will be. The orb, or allowable margin of error, for aspects between the Moon and Mercury is nine degrees.
If the Moon is within nine degrees of Mercury from adjacent signs, some of the benefits of this aspect will still be present. They will be greatly reduced, however.
The two people will be very different from each other, but they will understand each other better than they otherwise would given their differences.
