The Moon, being the planet of emotion; representing the mind and the mother, is in detriment in the sign of Capricorn. It’s natural ruler, Cancer, is where it thrives.

The moon rules Cancer, and it’s opposite sign is Capricorn. Oppositions in astrology create a bit of tension and a feeling of not quite being on the same page, even though they actually have a lot of similarities. Naturally, the opposite sign of any ruling planet has this sense of being uncomfortable about it, creating a “detriment” in it’s expression. Having a Capricorn moon is definitely an interesting experience. It can make you seem sad and serious, especially if you have it in the first house. In a nutshell, the moon in astrology represents your emotional responses, your mind, your mother. The Moon is an unconscious planet based on instinct. It’s not logical, it’s feeling. Many have attributed it to being one’s true nature, you at the core. It’s a hidden planet that’s characteristics are typically only known to people you have intimate relationships with — family, friends, partners, etc. Capricorn is an earth sign, ruled by the planet Saturn. It’s modality is cardinal, meaning it takes on leadership roles and it’s comfortable as a self-starter. Earth sign domain is the material aspect of life. Wealth, career and creating stability are important points. The planet Saturn is icy, cold and distant. Saturn is all about karma, restriction, responsibility, can be harsh and has little regard for emotions in any situation.
As you can imagine, even if you know nothing about astrology, Saturn’s influence on the moon can make one really uncomfortable with both feeling and expressing emotions. Capricorn moons likely grew up in an environment where they were expected to take on some level of responsibility from an early age. Whether this was often being placed in charge of siblings or helping to raise them or being expected to contribute financially to the family. Expectations from others can be very high; it can seem like Saturn is really testing these moons and their ability to succeed in all that is thrown on them. Saturn loves to challenge you, it’s what he does. But I attribute it to the fact that Capricorn moons are resilient and sometimes take on the responsibility just to test their limits. They can feel that they’re never doing enough.

There’s a restriction of emotional expression and affection that come with this placement. With Saturn being such a detached planetary influence, the inclination of the moon taking on this quality is a given. Their level of expression can be limited and their interactions can seem very cold and professional, almost businesslike. I’ve had several Capricorn moons share that they feel uncomfortable with hugs or physical affection, even from family members. Emotional outbursts from others can make them feel awkward. This would be considered more of the lower functioning nature of a Capricorn moon that still is in a stage of evolution. Normally a Capricorn moon would never allow themselves to have an outburst of any kind. They are always very cool and collected, but by no means does this equate to Capricorn moons being unfeeling creatures. I think many people believe Capricorn moons are heartless and cold because that’s what tends to be projected onto the world. This isn’t always far from the truth in some cases, but most have the capacity to feel very deeply. Although, their stoic outward expression would never let on.
The depression settles in when they feel heavy and weighed down. Somewhat of a somber state is what I would consider a Capricorn moon’s natural mood. There are always exceptions in astrology of course and aspects to the moon can definitely change this for the better. But when I think of a Capricorn moon, the first thoughts that come to mind are sarcasm and cynicism with a dry sense of humor. It can be difficult for some of them to feel satisfied with where they are, what they have and also to maintain a state of happiness. It’s almost as if they are in love with a feeling of melancholy. This is because the serious energy of Saturn is what they can feel most comfortable in. They can be labeled as pessimists, when they are actually realists that see things for what they are, not for what they want them to be. Sure, this is depressing as hell, but we all need someone to ground us into reality. I have a friend who is a double Capricorn, sun and moon. He has always been very practical and has never failed to give me advice from a logical perspective, which I appreciate. I’m usually too impulsive to think things through.

Always keeping everything inside can feel dark and burdensome. Capricorn moons tend to feel like they have to keep it together for everyone. They’re the strong ones, they feel like everyone is counting on them. Without hesitation, they will take on more work shifts and responsibilities when asked of them, even if they already have obligations occupying their time and energy. But they can handle the pressure. Saturn is tough, remember? Capricorn moons will keep people at a distance, even pushing them away when they feel someone managing to slip in. One of their major learning points is becoming more open and warm with others. They are afraid of being hurt and they are even more afraid of failure. Letting another person down or not feeling enough are huge issues for Capricorn moon people. Where some other zodiac signs might experience heart break or disappointment mainly in regard to romantic situations, success is everything for Capricorn moons. But it’s this same pressure to succeed that really drives them.
A depressed Capricorn moon is unmotivated and irritable. Their productivity plummets and their desire to accomplish tasks is no longer driving them. Grounding is important for all earth signs, and a helpful way to get them back into their nature would be to spend time in it. The moon is one of the most important placements in astrology and even though it’s in detriment here, Saturn offers an abundance of opportunities to grow.
