In astrology, your “Big 6” or “Big 3” refers to the sun, moon, Mercury, Venus, Mars, and your rising sign, which are the most important planets in your natal chart.
These planets, together with the rising sign, work together in your birth chart to describe your self-expression. Each of these celestial bodies has its own distinct meaning, and when combined with the zodiac signs, they add to your astrological compass (also known as your birth chart) and provide insight into a variety of your behaviors.
While the rising sign isn’t a planet, it is in the sign that represents the start of your consciousness. The sun, moon, Mercury, Venus, and Mars all reflect various elements of your life, personality, and how you connect with others, among other things.
Because these are the nearest celestial bodies to Earth, they have a greater impact on us than the outer planets (Jupiter, Saturn, Uranus, Neptune and Pluto). The sun and moon are the “mom and dad” of the sky, working together to transform light and being the only planets that never station retrograde.
Mercury, Venus, and Mars, on the other hand, station retrograde on a regular basis and have an impact on how we interact, connect, and express ourselves based on their direct or retrograde movement, as well as the signs and houses in which they are positioned in our birth charts.

What is the nature of my stellium?
When you map your natal chart, you can see the positions of all the planets in the sky at the time of your birth, not simply where the sun rises and sets.
“A stellium occurs when three or more planets are concentrated in a single zodiac sign or house in someone’s chart,” the twins explain. “Babies born in the summer of 2020 will have a stellium in Capricorn, because Jupiter, Saturn, and Pluto are all in Capricorn,” they explain. Having Mars, Mercury, and Saturn all in the fifth house is another example (which relates to romance, love, and creativity).
In some cases, people’s charts may have more than one stellium (i.e., three planets in Sag and three in the eighth house).
In astrology, what are the Big Three?
Growing up, you were undoubtedly asked what your zodiac sign was a few times. Perhaps you recognized yourself in the description, or perhaps it didn’t feel quite right. The reason for this is because your zodiac sign (also known as your sun sign) is simply a small part of your horoscope, whereas each of us has a full map of planets that influenced our birth. You may receive a much more realistic picture of your personality by learning about your full horoscope and all of its placements!
Finding out what your “big three placements” arethe sun, the moon, and the ascendantis the first step in getting to know your horoscope. These three planets each represent a different aspect of you, and when combined, they form a remarkably accurate portrait of your personality. Here’s a quick rundown of these opportunities.
What is your ascension?
The majority of us are aware of our own and our friends’ star signs, also known as sun signs. Isn’t it how we all make passive aggressive judgments while bigging ourselves up on Instagram with zodiac memes? Our moon signs are also known to us. But did you know you have a RISING SIGN that’s just as important?
The planetary influence that was rising, i.e. on the Eastern horizon, when you were born is your rising sign. It usually reflects how others perceive you in real life and can predict your gut reactions to situations. It is, however, yet another potential personality flaw to consider.
Because of its connection to the rising sun, your rising sign is also known as your ascendant, and many people associate it with your social nature, it’s possible that if someone is guessing your sign, they will get your rising sign before your sun sign! It’s how other people perceive you, which is something you’ll never have. This makes it a fascinating aspect of your birth chart to investigate: discovering who you are in the eyes of others.
Is a stellium an uncommon mineral?
If you’ve ever encountered someone with a powerful personality who appears to have all of the qualities of one sign, they may have been born with a stellium. It may seem terrible, but it is truly unique and quite unusual.
Is Midheaven considered a stellium?
A stellium is a grouping of three or more planets that appears in a person’s birth chart. These three planets, plus one, must all be in the same house and sign. These planets may or may not be in conjunction, however this is not usually the case.
Some astrologers disagree with this description, but it is one of the more frequently accepted ideas, and I have found enough evidence in my experience to support the theory that stellium energy is created by three or more planets.
In the example above, you can see that this person has a three-planet stellium in Pisces’ 9th house (Chiron, Mercury, and Neptune) and a four-planet stellium in Pisces’ 10th house (Mars, Moon, Sun, and Venus). Uranus, despite being in the 10th house, is not a member of the stellium because it is in the sign of Aries. Because it is neither a planet nor a luminary, the Midheaven is not included in this stellium.
The Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, and Chiron are the only luminaries/planets that make up a stellium. Stelliums do not contain things like the North Node, South Node, Ascendant, Descendant, Midheaven, and so on because they are not physical bodies.
Stelliums reflect the native’s seat of power, as well as a concentrated attention on that house’s location over the native’s lifespan. Whatever sign the stellium is in will be an important component of that person’s personality, representing reasons and themes within the house’s greater lesson.
The absence of stelliums in a chart does not indicate anything undesirable or harmful. It’s fine if many people don’t have them. It simply indicates that there will be greater balance in life themes, rather than a single focus or preoccupation throughout one’s existence.
Stelliums are frequently employed in the study of cultural or mass events. When a stellium appears in the chart during a historical or present event, it indicates that the event is imbued with the energy of that house and sign. We’ll go over that in greater detail in a later piece.
You must look at the house the stellium is in and what that house represents in order to understand how the stellium’s energy will manifest. Houses frequently depict external events in our life, while the sign of the planets in this house depicts how we respond to these events. The 9th and 10th house stelliums of Pisces, for example, imply an emphasis on broad thought, philosophy, and travel (9th house) and economics and stability (10th house), which are handled in a sensitive, dreamy, almost unconscious manner in the sample chart above (Pisces). It will be natural for the native to devote a significant amount of mental energy to speculating on possibilities, and they may even make a career out of it. The stellium of the 10th house shows a propensity for leadership, but as Pisces is the sign of “martyrdom,” the native may take on leadership duties in order to aid others to the point of stress.
Also, keep an eye on which planets are present in the stellium. The presence of some planets, such as Pluto, could imply that the stellium’s energy has a compulsive nature. Neptune could indicate an unconscious aspect, implying that the native is unaware of the stellium’s energy. Uranus will give the stellium’s essence a new twist (i.e. Uranus in a 2nd house stellium will encourage the native to earn money through a unique career). Saturn will teach you lesson after lesson about the theme of the house.
What is a Grand Trine, and how does it work?
“That implies they must all belong to the same element (fire, earth, air, or water), and one planet must pass through each of the three signs in that element. In a grand trine, the planets are at a harmonious 120-degree angle to each other, which is known as a trine “They also add.
Grand trines are generally regarded to be fortunate because the planets are joyously basking in the same element, speaking the same language and vibrating off each other, according to the twins.
By looking at your birth chart, you can check if you have a grand trine (see here to calculate it). There will be an equilateral triangle in the center, and at least three planets will be in one element. (For an example, see the image below.)
What are the signs of the moon?
Your moon sign is the zodiac sign in which the moon was at the time of your birth. It’s the soul of your identity, the hidden part of yourself that you may keep hidden from others (unlike your outwardly appearing sun sign), and it accounts for a significant portion of your emotional side.
