Each person is uniquely represented by his or her natal chart; no two are the same. Even identical twins who are born within a few minutes of each other may have different ascendant (or “rising”) signs, which changes the orientation of the chart by a few degrees, just enough to give each placement (a planet-sign combination) an entirely different context for expression (the houses). This can cause profound differences in behavior and life paths even though the identical twins will have all of the same placements. Even if they do have the same ascendant, the few minutes that separate them will turn the natal chart ever so slightly, causing the “aspects” to have slightly different “orb values”, which will cause a difference in the strength of each trait that those aspects represent. As I am sure you are already lost by these terms, this brings me to the first set of technical things that I have learned about astrology.
First, you are more than your “sun” sign, which is typically the only sign that people are aware of. It is also referred to as the “star sign” or “zodiac sign”, but these are newbie terms. The sun is one of many planets in the birth chart, and it is associated with only one part of a person’s personality, albeit an important one: the ego – the default personality mode in which one operates around people with whom he or she is fairly well acquainted. It is usually the style of personality by which you want to be seen. Your sun is released and shows up with someone once you’ve “broken the ice” with them. Most people who know a little bit about astrology are still only aware of their “big three” signs which includes the sun as well as the moon which is the emotional, internal center and that part of one that one likely identifies with when one is alone, and the ascendant (or “rising” as it is more commonly referred to) which is the unconscious mode in which one operates in new and unfamiliar situations.
To get a bit more technical, there are three parts to astrology that are vital for understanding anything in greater depth: signs, planets, and houses. Signs are constellations such as Aries or Libra, and they represent styles of expression. Aries is an aggressive and impulsive, yet socially-attractive style, while Libra is a style concerned with balance and fairness, also typically attractive to others in a slightly softer and more charming way than Aries. A planet, the sun and the moon included, is the particular part of your personality. When a constellation is inline with a planet, a particular expression style is being applied to the part of your personality represented by that planet. The houses are the pizza slices of a chart; they are the contexts of life in which those personality styles occur.
To tie all of this together in an example, Venus, which is the feminine, sensual, social, and romantic side of someone, can be in Gemini, which would value intellect, variety, and fun in romantic relationships. Let’s say that placement were in the 2nd house in the birth chart, which is the context of money and material possessions. When Venus in Gemini is expressed in the 2nd house, that could, depending on what else is going on in the birth chart, be an indication that one would have a tendency to be a sex worker (and really enjoy it). My Venus is in Gemini, but it is in the 5th house which is the context of creative self-expression, entertainment, and romance, so although this placement makes me a bit of a hoe, it works quite well here as my sexual and romantic relations are reserved for creative and recreational fun and — when paired with masculine Mars in Aries in the second house (the context of communication) — writing erotic poetry. An empty house indicates a lack of value placed on the context that house represents. For example, my 2nd house has no planets in it, so I don’t care much about money or material possessions. This is why I am not a sex worker. See? Shit’s complex.
The specificity of a part of a chart often indicates its complexity and importance. The sun sign isn’t very specific. It is sort of a general box, a “type” as in MBTI, that you’re shoved into when one isn’t aware of the other parts of a chart. One might say to another “We’re both Cancers, so we’re totally like the same person omg.” Their egos may be similar, but there are plenty more layers to the personality, such as the other placements and the house in which the sun is situated, that will add virtually infinite complexity to the role that the person’s ego plays in their life and therefore to the degree of differences between Cancer sun people. The sun sign changes about every thirty days. Is everyone who was born from late June to late July, with their sun in Cancer, the same? Of course not. In my research so far, and in simply introspecting on the fact that my sun, for example, is in cancer yet my personality doesn’t seem to identify with that style, I think that the degree to which your sun sign matters is roughly equal to the degree to which one has awareness and control over his or her own ego. Fire suns (Aries, Leo, Sagittarius), for example, are hard to control. They tend to be quite self-centered and easier to spot. Fire reacts when you pour gas onto it, after all.
Sun sign discrepancy could also be due to the degree to which the ego is suppressed by a more dominant force ruling the birth chart on the whole. Look at the birth chart on the whole. Is there a sign that dominates your chart that is not the sun sign? If so, especially if that sign has key placements in the moon or ascendant, this might be the reason that you don’t identify with your sun sign. For example, my Cancer sun is squashed by my stronger and more abundant Capricorn planets, so I come off more as a Capricorn than a Cancer. Even professional astrologers I have met were shocked to find that I was a Cancer sun person.
There is also a way to calculate why you may not identify with your sun sign. This takes us into a secondary set of terms needed to understand astrology in a technical way. Each sign has a unique “element” and “modality” combination. Elements (fire, earth, air, water) are attitudes that signs have, whereas modalities (cardinal, fixed, mutable) are roles that the signs play. Your dominant sign may not be a sign that shows up in any placements in your chart at all, but it may be the dominant element/modality combination of the chart on the whole. For example, Taurus may not show up in your chart, but because your chart is comprised of more earth and fixed signs than anything else, the person could carry a Taurean energy on the whole, seeming “unchanging in your ways” due to the fixed dominance of your chart and “grounded” in attitude due to the earth dominance.
If there is one specific area of astrology that seems to provide the deepest insight into the whole of human psychology, it is the aspects. An aspect in astrology is a relationship between two planets that forms a more complex and unique energy. Aspects show up within someone’s birth chart and between the charts of two people. Contrary to what pop astrology may have you believe, it is aspects, not signs, that are the most important parts of a chart. Whereas a sign represents a style of expression of a particular part of someone’s personality, an aspect combines the styles between two parts of oneself, providing more substance about what someone is like. The type of aspect is determined by the angular relationship between those planets.
A CONJUNCTION between two planets means that they fall at or near 0 degrees of each other and therefore likely share the same sign and house, but they may not if they are on a cusp. Either way, these two parts of one’s personality will be in harmony with one another. It is as if one part of yourself has seamless communication and understanding with that other part. The most common example is Sun-conjunct-Mercury which means that there is a fluid connection between one’s ego identity and their style of communication. A conjunction is thought to be a positive aspect, and it usually is. I think, however, this can blur lines too much at times just as two people who are very similar can lose their senses of individuality when together. There are clearly times in which one should be able to separate conjuncted parts of his or her personality (e.g. romance and work) and reflect on which part needs tweaking in order to make better decisions in the long run. For example, if one’s sun and moon are in a strong conjunction, it means that one has trouble understanding whether he or she is acting from ego or from emotional reflection. Neither way is entirely good in my estimation. This person may need to work extra hard to understand where the origins of their behaviors lie. I have a friend, for example, whose sun and moon are both in Virgo. She makes quick and confident decisions, but she often winds up in a hot mess because she doesn’t take time to think about why she is so confident in that decision. I have another friend who is a double Taurus. Equally confident and simple-minded in her decisions, she moves more slowly and carefully, so she doesn’t find quite as much trouble. She still, however, lives with some regret about her decisions later on. The style that a conjunction takes on depends on the sign, but in any case, this harmonious aspect comes with challenges. A good rule to keep in mind while dealing with matters related to a conjunction in you chart is: “separation, then integration”. We have to understand our individual bits in isolation before we can make them work together in a way that aims us toward the true potential that a conjunction can afford.
An OPPOSITION aspect is when two placements fall within or near 180 degrees of each other, meaning that they are directly across from each other in the chart wheel. They fall in signs and houses that seem on the surface to be opposites. One should not think of them as opposites, however, but as being in opposition with one another. They are shadows of one another, to speak in Jungian terms – two sides of the same coin, each wishing at times that the other did not exist. They have the same modality but different elements, so they play tug-of-war with each other, struggling for power. This inner tension may be felt very deeply by the individual and stunt decision-making ability. The opposition is often regarded as an adverse aspect, and it often is. However, I think it is the best aspect when it involves key planets. As someone who has a chart dominated by opposition aspects, I can firmly say that this presents the greatest and most necessary opportunity for growth of any aspect. I see it not as a struggle for power, but as a struggle for balance, for both sides of the personality must learn to coexist. At 180 degrees they are at opposite ends of the universe, so to speak, but they forced to face each other from afar. When balance between them is found, another level of self-awareness and confidence is reached, and people notice it. I have personally been told that I possess a very balanced personality. The reason is because of all of my opposition aspects between my Cancer and Capricorn planets and the degree to which I consciously seek balance between them.
Whereas the adverse nature of the opposition presents an opportunity to grow, planets in a SQUARE aspect are usually better off avoided. This is a 90 degree relationship between planets that creates perpendicular lines through the center of the chart; it the most harsh relationship between any two parts of one’s personality. These planets will be expressed through signs that are three removed from each other, so they will be similar in modality but not in element. This means that they want to play the same role but have incompatible styles in which they do so. It is never a case of opposites attract as it is in an opposition, but rather, these two parts of oneself will constantly be in competition with one another, struggling for power. They will create difficulty because there is a lack of understanding between them and often a stubborn unwillingness to come to an understanding. My Capricorn ascendant and Aries Mars (the masculine, action-taking, and sexual part of one’s personality) have a strong square aspect. This can lead me to come off as very argumentative and abrasive with certain new acquaintances, especially if I perceive them as ignorant and weak. Both Capricorn and Aries have leadership tendencies, but in styles that don’t see eye to eye. Whereas opposition placements such as Capricorn and Cancer are at 180 degrees and play father/mother roles, Aries will be pointed north when Capricorn is pointed east. They see past one another as they are literally aiming in different directions. When they are forced to work together, it is typically best for them to find structured roles in which they are both naturally suited and to stay out of each other’s way.
Learn your square aspects if you have any, and keep those parts of yourself compartmentalized whenever possible. On the relationship side of things, there are no two sun sign people who cannot make it work if both are willing. As a Cancer sun and a Capricorn-dominant chart, I have issues making it work with Aries women as most of my planets will be squared to her sun. This difficulty comes solely down to an ego battle, so if two people can leave their egos at the door, then there is no firm reason why a relationship between two square sun signs cannot work. In fact, a romantic relationship between to squared suns can be ego-shattering and therefore extremely fruitful for the personal growth of each individual. My brother is an Aries sun, and his girlfriend is a Cancer sun. There is nothing else in their composite chart to indicate that they would be incompatible for any other major reason, and as it turns out, they have an extremely harmonious and relatively ego-free connection. Of course, it helps that my brother’s ascendant and moon are both in Cancer.
The SEXTILE is a type of aspect that places the two planets at or near 60 degrees apart. There is usually, but not always, one sign between the signs of those two planets, so sextile sign pairings (e.g. Aries + Gemini with Taurus between them) share neither an element nor a modality. What they do share, however, is yin (earth + water) or yang (fire + air) energy., so they complement each other in the key ways. They have different reasons for valuing similar things and different ways of achieving many of the same goals. There is a lot of agreement between them about what needs to be done and respect for each other about their differing styles on how to do it.
TRINE planets are about 120 degrees apart and usually fall within four planets and four houses of one another, so they share an element but not a modality. One comfortably cedes control to the other, but they are similar in their grounding. Cardinal Capricorn and mutable Virgo are compatible signs, for example. Capricorn takes on a leadership role and Virgo a more following role, and they feel comfortable in this dynamic since they are both “grounded” and “in their element” as earth signs. My chart, for example, is Capricorn dominant, and I find myself highly attracted to Virgo women. There tends to be an understanding and acceptance about our lifestyle choices and personality quirks, and I am able to express my natural cardinal decisiveness with the comfort of knowing that she will not only go with it but will also generally agree that the right decision is being made for us both.
There is one aspect that is often overlooked, and when it occurs in one’s natal chart, one should be made aware of it. It is not always considered a major aspect, but I think it should be. That is the INCONJUNCTION (or QUINCUNX). Whereas the trine at 120 degrees is seen as a nice, complementary aspect and the opposition at 180 degrees is seen as a challenging one, the quincunx is at 150 degrees. These two placements are completely neutral toward one another, for they share neither element nor quality and are distant from one another. They therefore lack an understanding and any ability to communicate. They speak different languages, have different goals, and deeply value different things. These two parts of one’s personality will be naturally compartmentalized and kept separate unless they encounter a tremendous stroke of harmonious luck. My Venus, for example, is in Gemini, which is already a taboo placement as it means I’m kind of a whore. To make matters worse, it is inconjuncted with my Midheaven in Scorpio which deals with career ideals. Details aside, what this means is that my romantic pursuits, and even platonic friendships, seem to be things that I cannot reconcile with the vision I have for my career potential. I often feel I am at a crossroads between having to choose love/friend interaction and work toward my bigger goals. Gemini and Scorpio are two signs that are infamous for not being on the same page when it comes to organizing time and priorities. An inconjunct between two of your placements will make you feel that confusion very deeply. As a side thought, I would suspect that many wrong decisions in life made by people, who are otherwise perfectly self-aware, are the result of a inconjunct/quincunx between two key planets in a birth chart.
I hope that the technicalities that I have just described are somewhat clear. I suspect that most writing about astrology that is to come will be about the aspects, so I wanted to lay out these descriptions as a foundation for future posts.
