Sun conjunct Moon is a complicated aspect in synastry. Much will depend on the sign, whether the two people were born during the day or at night, and the other synastry aspects involved.
The Sun is the Luminary of the Day, and the Moon is the Luminary of the Night. As Luminaries, the Sun and Moon are involved in every aspect of our lives, which includes our relationships.
Almost everyone knows about Sun Signs. Indeed, they are the part of astrology that most people learn first. Yet, Sun Signs are not always the most important planet in a person’s chart.
The Sun is not even always the dominant Luminary. If someone was born at night, or if the Sun is otherwise weakened in their chart, the Moon can be the dominant Luminary.
A conjunction is a neutral aspect. It occurs when two planets are together in the zodiac. In synastry, it shows similarities between two people. This can be positive or negative.
Sun Conjunct Moon in Synastry
When the Sun is conjunct the Moon in synastry, it creates a powerful connection and a deep bond between people. This aspect is quite common between family members, especially between parents and children.
When it occurs in a romantic relationship or a friendship, it will also create a deep bond. This bond will be complicated, however, in the same way that bonds between family members can be.
The reason that this aspect is so complicated is that it can cause people to become enmeshed with each other. It can be hard to determine where one person ends and the other begins.
Sun Sign astrology is quite popular, and it is often a person’s first exposure to astrology. But, the Sun Sign is not always the dominant Luminary in a person’s birth chart.
If they were born at night, the Moon will usually be the dominant Luminary. Because of this, in analyzing this aspect it is important to consider whether the people involved were born during the day or at night.
The signs are also divided into day and night signs, and this is known as sect. This aspect will behave differently depending on what sect it occurs in.
The day signs are Aries, Gemini, Leo, Libra, Sagittarius, and Aquarius. The Sun prefers to be in these signs.
If the conjunction falls in any of these signs, the person whose Sun is involved will tend to be the more dominant of the two. This is especially true if it occurs in Aries or Leo.
Even though Libra and Aquarius are day signs, they tend to hamper the Sun for other reasons. This will make for a more equal relationship.
Taurus, Cancer, Virgo, Scorpio, Capricorn, and Pisces are the night signs. The Moon is stronger in these signs. In these cases, the person whose Moon is involved will gravitate towards taking the lead.
The Moon is especially strong in Taurus and Cancer.
The Moon has trouble in Scorpio and Capricorn even though they are night signs. In these cases, the person whose Sun is involved will provide stability for the other.
The house that this conjunction resides in the charts of both people will give details as to how the conjunction will manifest.

Man’s Sun Conjunct Woman’s Moon Relationship
Any time the Sun is conjunct the Moon in synastry, one person’s life will tend to revolve around the other. This is especially true in a romantic relationship. When it is a man’s Sun conjunct a woman’s Moon, her life will revolve around his.
The Sun and the Moon are both Luminaries, but they operate very differently. The Sun’s job is to shine and bring light and warmth. The Moon’s job is to govern the practical details of life.
As a metaphor, the Sun is the Monarch, and the Moon is the Prime Minister. She might have a lot of control in the relationship, but in a sense, she will still be overshadowed by his light.
This may or may not be a problem for the relationship. Much will depend on both of their temperaments, and the other aspects between them.
They may have to actively create some separation between them so that they do not become enmeshed with each other.
Woman’s Sun Conjunct Man’s Moon Relationship
This situation is similar to that in which the genders are reversed. In this case, however, it will be his life that will revolve around hers.
This relationship may or may not include a gender role reversal. Even if they maintain rather traditional gender roles, however, he will adore her and feel like his main role is to support her.
It will be important for both of them and for the health of the relationship that they each find their separate identities. This aspect creates a strong risk of unhealthy enmeshment between the two.
Sun Conjunct Moon in Friendship
The Sun conjunct Moon in synastry will create a very close friendship. In many ways, the two will be closer than family or than either of their romantic relationships.
The person whose Moon is involved will tend to focus strongly on the person whose Sun is involved. There could also be an unhealthy enmeshment between the two.
This friendship could threaten either or both of their romantic relationships, and either or both of their romantic partners could become jealous of their closeness.
It will be important to look at the other aspects between the two in analyzing this aspect.
How to Tell if the Sun is Conjunct the Moon in Synastry
On a basic level, if one person’s Sun is in the same sign as the other’s Moon, the influence of this aspect will be present.
The orb, or allowable margin of error, between the Sun and the Moon is fourteen degrees. In the case of the Sun conjunct the Moon, this aspect is more problematic the closer it is to exact.
It is possible for the Sun and Moon to be within fourteen degrees of each other from adjacent signs. For most practical purposes, a cross-sign conjunction between the Luminaries can be ignored unless it within one or two degrees of each other.
Even in this case, the more negative qualities of this aspect will be neutralized. The sign boundary will prevent the two from becoming too wrapped up in each other.
