How to find your Big 3 in astrology

The first step in finding your Big 3 is to pull up your natal chart. If you have never done this before you will need the exact time and place of your birth. If you don’t have access to that information, there are astrologers who will “rectify” your chart, meaning they will ask you questions about important events in your life and figure out your Big 3 for you.

If you have that information but haven’t ever looked at your natal chart, you can get a copy for free at Astro Dienst. Once you create an account, this fantastic site will store your chart for future use.

Once you have your chart, let’s find your Big 3!

Finding your Sun

On your birth chart, your Sun is going to be the symbol that looks like this.

In the example chart above, you can see the symbol circled. It sits in the sign of Sagittarius and the 6th House. For this person, they could say that they are a Sagittarius Sun in the 6th House.

Sometimes, it may be difficult to tell what sign a planet sits in if it is close to a boundary line. In Astro Dienst, there is a handy table below your chart where you can also find the signs of important features.

In the table above, you can also see that this person’s Sun is in Sagittarius, abbreviated as “Sag.” From the degrees noted next to “Sag,” I can tell that the Sun barely sits in this sign.

Finding your Moon

The Moon symbol is easy to remember because in astrology it looks like this ☽.

In the chart above, you can see the Moon symbol, ☽, circled and that it is in the sign of Taurus and in the 11th House.

Finding your Ascendant or rising sign

The final piece of the puzzle when finding your Big 3 lies with your Ascendant, shown on the natal chart as AC. Your Ascendant isn’t a celestial body. It is an angle on the chart that represents where the eastern horizon was at the moment you were born.

The Ascendant looks like a line and it marks the beginning of your 1st House. You can find it positioned cutting through the center of your chart on the left side.

Your Ascendant will never have a different house to find as it always marks the start of your 1st House, but it will always have a sign.

The sign of your Ascendant is referred to as your rising sign. You can see in the example chart above that the sign of their Ascendant, their rising sign, is Cancer.

So finding your Big 3 is simple! You simply look for your Sun , Moon ☽, and Ascendant, or “AC” on your chart.

What are my 3 Zodiac signs?

Your 3 Zodiac signs in astrology are the sign that your Sun sits in, the sign of your Moon, and the sign that your Ascendant is in. The Ascendant is a line on your chart and whatever sign this line resides in is called your rising sign. Your rising sign, Sun sign, and Moon sign are your 3 Zodiac signs.

Most of us are introduced to our Sun signs first, as that is what we look for when we read the horoscopes. But, all 3 Zodiac signs are important and they all mesh together to create who we are.

Why your Big 3 in astrology is important

So you found your Big 3 in your natal chart, but why are these three things so crucial? Why are your Big 3 so important in astrology?

The Big 3 in astrology are important because they lay out the framework of your personality and your soul’s experience in this lifetime. Your Sun details how you identify yourself, your Moon represents how you process and react to emotions, and your rising sign symbolizes how you present yourself to others.

When considering other factors in your chart and how you may express them, it is always helpful to keep your Big 3 in mind. Jupiter in Scorpio in the 5th House, for instance, would be experienced differently by someone with a Sagittarius Sun, Taurus Moon, and Cancer rising than it would be for a person with a Capricorn Sun, Virgo Moon, and Aquarius rising.

The Big 3 lay the groundwork and interpreting your Sun, Moon, and Ascendant is a great place to begin when reading your chart. Even if you stop there, you will have gained valuable information about yourself.

You can think of your Big 3 as the three main building blocks of your personality upon which all of the other details of your life experience will be built.

Other important factors in the chart

As you have read, the Big 3 are definitely vital when reading your natal chart, but they are the only pieces of the puzzle, of course? So once you have found and investigated your Big 3, where do you look next?

One great place to start is to look to your chart ruler. The chart ruler is the planet that rules your rising sign.

In the example chart we looked at earlier in the article, we saw that this person’s Ascendant sits in the sign of Cancer. That means that their rising sign is also Cancer.

The ruler of Cancer is the Moon. So, this person’s chart ruler is also the Moon.

Because your chart ruler has so much influence on how you present yourself to the world through your Ascendant, it is an important planet in your reading and may have more pull. Where it is positioned in your chart will help to add more detail to your outward personality and how you come off to others.
