Sun square Moon is a tough aspect in synastry. It can bring tension and make it hard for two people to understand each other.

The Sun and Moon are the two Luminaries. The Luminaries show who people are on a fundamental level.

They play a role in almost every aspect of life, including our relationships.

A square generates tension and friction. In synastry, it shows areas in which two people annoy each other. On the other hand, the tension can also turn into physical chemistry in romantic relationships.

Sun Square Moon in Synastry

Sun square Moon is one of the more challenging aspects in synastry. It signifies fundamental differences that are not easy to overcome.

Yet, this aspect also generates chemistry. This means that it can help a relationship to form, even if that relationship is filled with tension.

One of the reasons that is aspect is so difficult is that it is not easy to identify the traits that they find annoying about one another. It goes to matters that are fundamental to each of their personalities.

In many ways, Sun square Moon can create a push/pull, love/hate relationship. The two struggle when they are together, but they also keep seeking each other out.

As with any aspect, it is important to consider the other aspects between the two charts.

Mercury is always within one sign of the Sun. This gives a good chance of one person’s Mercury being in a positive aspect with the other’s Moon. This will go a long way to mitigate the difficulties of this aspect because the two will be able to talk through their difficulties.

Also, look to see if there are favorable aspects between the Moon and Venus. These will go a long way towards the two having good feelings toward one another despite their differences and help them to reconcile when they quarrel.

In addition to the other aspects, there are certain sign combinations that will change the meaning of this aspect.

Sun in Cancer

The Moon is the ruler of Cancer, so if the Sun is in this sign, this person will be much more receptive to the other person.

If the Moon is in Aries, the positive feelings will be mutual, and the two will get along better than they otherwise might.

If the Moon is in Libra, however, this will be one-sided. The person whose Sun is involved will have less tolerance for the other.

Sun in Taurus

The Moon is exalted in Taurus, so the person whose Sun is involved will tend to have positive feelings for the other, even if they clash.

If the Moon is in Leo, which is the sign the Sun rules, this will go both ways. They will still have conflict, but as a general rule, this sign combination is more positive than negative.

On the other hand, if the Moon is in Aquarius, the person whose Moon is involved will tend to reject the other.

Sun in Capricorn

In general, this aspect will be worse if the Sun is in Capricorn. Capricorn does not like the Moon, no matter what sign it is in.

If the Moon is in Aries, that person will be strongly attracted to the other person, which may be enough to overcome the otherwise difficult effects of this aspect.

If the Moon is in Libra, however, the dislike will be mutual. This aspect and sign combination may be fatal to the relationship unless there are other more positive aspects between them.

Sun in Scorpio

Scorpio is another sign that is hostile to the Moon, so this will tend to make this aspect worse than usual.

It will not be quite as difficult if the Moon is in Leo because the person whose Moon is involved will tend to idolize the other.

It will be even more difficult if the Moon is in Aquarius. To determine if there is a strong enough basis to hold the relationship together, it will be important to consider the other aspects between them.

House Position

The houses that the planets fall in each other’s charts will show the areas of life that will be impacted by this aspect the most.

Her ego and pride come into direct conflict with his more sensitive and tender side.

Sun Square Moon in Friendship

Difficult aspects such as Sun square Moon often do not create as many difficulties between friends as it does between romantic partners.

In part, this is because if there are not other more harmonious aspects, they probably will not become friends in the first place. This is particularly true if a romantic relationship is impossible because of their gender and sexual orientation.

If a romantic relationship would be possible, one or both of them might have a crush on the other. It is more likely that the person whose Moon is involved will develop the crush, but it could go either way.

If the happens, it could spell trouble for the friendship. In most cases, it is best not to indulge such romantic feelings unless there are other indications in the chart to support that.
