The western zodiac, which consists of 12 constellations: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces, is one such tradition.

What is the order of the 12 zodiac constellations?
Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpius, Sagittarius, Capricornus, Aquarius, and Pisces are the 12 zodiac constellations, and you’re definitely familiar with them thanks to astrology.
What makes the 12 zodiac constellations so unique?
The 12 signs of the zodiac, as mentioned in a horoscope, are inextricably linked to the Earth’s motion through the sky. The constellations that point out the path that the sun appears to take during the year provide us with these indicators. Dates in a horoscope may appear to match to when the sun travels through each constellation. They don’t always agree, though, because astrology and astronomy are two separate systems. Plus, a closer look at the Earth, the sun, and the stars reveals that the zodiac is more complicated than you might think!
The sun’s motion through the constellations
The sun appears to pass in front of numerous constellations as Earth revolves the sun. The sun’s position in relation to distant background stars drifts in an easterly direction from day to day, much how the moon appears in a little different spot in the sky each night. It’s not as if the sun isn’t moving. Its movement is totally fictitious, owing to Earth’s own rotation around our star.
The sun appears to be in front of, or “in,” different constellations throughout the year. The sun appears in Gemini one month and Cancer the next. The dates in the newspaper’s horoscope indicate when the sun is in a specific astrological sign. For example, the sign Aries is represented by the period between March 21 and April 19. However, your astrological sign does not always indicate which constellation the sun was in when you were born.
Why the zodiac constellations don’t always align with astrological signs
We need to know a little bit more about how the Earth moves to explain why constellations no longer coincide with their respective signs. We must also discuss how we measure time.
Time is a fiendishly difficult concept to grasp, especially if we insist on using the sun and stars as our point of reference. For better or worse, our calendar is based on the seasons. The day the sun appears at its most northerly point in the sky is June 21, the approximate date of the summer solstice north of the equator and the winter solstice south of the equator. The North Pole is most inclined towards the sun at the June solstice.
The fact that the North Pole does not always point in the same direction as the background stars complicates things. Our world whirls around like a top. The Earth, like a top, wobbles! The North Pole traces a circle on the celestial sphere due to the Earth’s wobble. The wobbling is slow; it takes 26,000 years to complete one rotation. However, as time passes, the effect becomes more pronounced.
The direction of the Earth’s axis drifts somewhat throughout the course of one orbit around the sun. This means that the location of the solstice along our orbit changes by a very modest amount. The solstice occurs around 20 minutes before one full trip in front of the background stars!
Our drifting calendars
Because we base our calendar on the solstices and equinoxes (and astrologers on the signs), the Earth does not complete an orbit in a single year. The tropical or seasonal year is really a fraction of a second shorter than one full orbit (sidereal year). This means that the sun’s position in relation to the stars on any particular day varies throughout the year. For example, on June 21, a very small amount of snow falls.
However, after 2,000 years, the sun will be in a completely other constellation!
The sun was nearly halfway between Gemini and Cancer on the June solstice 2,000 years ago. The sun was between Gemini and Taurus on the June solstice fourteen years ago. In the year 4609, the June solstice point will move from Taurus to Aries, leaving Taurus behind.
When humanity formed the present Western zodiac some 2,000 years ago, the signs were roughly aligned with their respective constellations. However, the steady wobble of the Earth’s axis has led the solstice and equinox locations to shift around 30 degrees westward relative to the constellations in the intervening ages. Signs and constellations are currently around one calendar month off. They’ll be approximately two months away in another two thousand years or so.
Modern constellations and the zodiac
To make matters even more complicated, unlike astrological signs, constellations are not all the same size and shape. For the most part, the stars that make up a constellation are not physically related. They’re simply based on patterns that our forefathers noticed when they looked up at the sky, trying to make sense of it all.
The International Astronomical Union (IAU) established the constellations as sky regions, not only star patterns, in 1930. They established the boundaries we use today as a result of this. These current constellations are based on those introduced in the second century CE by Greek astronomer Ptolemy. He, in turn, took them from Babylonian scriptures dating back thousands of years. Throughout history, several societies have seen patterns in the sky that are unique to them. Some constellations are shared by many cultures (Orion is a good example), but not all.
There are actually 13 constellations that lay along the path of the sun, based on the present borders. Ophiuchus, the Serpent Bearer, sits between Sagittarius and Scorpius and is not mentioned in any horoscope. The signs stay stable in relation to the solstices and equinoxes, while the solstices and equinoxes shift westward in relation to the constellations or backdrop stars.
While the zodiac isn’t a fantastic predictor of love, fortune, or health, it is an excellent tool for better understanding the sun’s, Earth’s, and even the cultures that have come and gone on our small planet. The zodiac signs, which are drawn from constellations that line the path of the sun in the sky, trace Earth’s orbit and wobble and serve as a reminder of astronomy’s humble beginnings.
Bottom line: While you may identify the term zodiac with astrology, it also has a prestigious role in astronomy. The 12 constellations that make up the zodiac are located along the sun’s annual motion across the sky.
What are the names of the 12 zodiac signs?
The zodiac is a belt-shaped section of the sky that stretches approximately 8 degrees north or south of the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year (as measured in celestial latitude). The Moon’s and visible planets’ courses are all within the zodiac belt.
The zodiac is divided into twelve signs in Western astrology, and formerly astronomy: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. Each sign occupies 30 degrees of celestial longitude and roughly corresponds to the star constellations: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn
These astrological signs make up a celestial coordinate system, or more specifically, an ecliptic coordinate system, in which the ecliptic serves as the origin of latitude and the vernal equinox serves as the origin of longitude.
What are the names of the seven primary constellations?
We chose seven of the most well-known constellations from both the Northern and Southern hemispheres for this infographic: Ursa Major, Cassiopeia, Orion, Canis Major, Centaurus, Crux, and Carina. You can simply locate any of these constellations in the sky using our short suggestions. Any amateur astronomer who wants to learn about notable constellations and asterisms will find our infographic useful. If you like this infographic, please share it with your friends!

How many constellations are there in the zodiac?
First and foremost, you have our permission to refer to yourself as a Lupus or a Lyra. People form attachments to a variety of constellations, not just those in the “zodiac.” Out of the 88 zodiac constellations officially classified by the International Astronomical Union, we acknowledge 13 of them. The Zodiac constellations are the ones that the Sun appears to travel through throughout the year. Of However, because the Earth revolves around the Sun and hence the Sun’s position relative to the background stars changes constantly, this motion is illusory.
The Sun appears to be travelling through Virgo the Maiden right now. The Sun will enter Libra, the Scales, at the end of October. The Sun then travels through Scorpius the Scorpion, Ophiuchus the Serpent Charmer, Sagittarius the Archer, Capricornus the Seagoat, Aquarius the Water Bearer, Pisces the Fish, Aries the Ram, Taurus the Bull, Gemini the Twins, Leo the Lion, and finally back to Virgo the Maiden, where the cycle begins again.
The Sun happened to pass through these thirteen constellations because they were oriented in such a way. We could change Earth’s orbit so that the Sun seems to pass through different constellations if we wanted to (and had supernatural powers). Lupus and Lyra, on the other hand, cannot be zodiac constellations because the Sun does not “travel through” them.
If the Sun was in that constellation when you were born, you were termed a “Virgo” or “Leo.” The astrological calendar, on the other hand, does not account for precession. The constellations aligned along the Sun’s path, called the ecliptic, shift stations slowly over time, by about one degree every 73 years, as the Earth’s poles precess over a 26,000-year period. The dates associated with the zodiac by astrologers were valid roughly 2,000 years ago. On the first day of Spring, for example, the Sun was in Aries. It is now in the sign of Pisces. As a result, astronomers continue to refer to the “First Point of Aries” on the first day of Spring (Vernal Equinox).
What are the signs of the zodiac that I belong to?
When people inquire about your zodiac sign, they usually mean your Sun sign. And, to be honest, everyone knows what their Sun sign is. It’s easy to check it up now that we have the Internet, and at the very least, everyone has been intrigued about what the stars have to say about them. Some people completely identify with their Sun sign, while others find it completely incomprehensible.
There are a number possible explanations, including your Moon sign and Ascendant, which I’ll discuss later. Even if you don’t exactly relate to the attributes of that zodiac sign, from the perspective of the sky, you will find patterns that correlate due to planetary motions at any given moment, thus I always urge people to read for the Sun sign in daily/monthly/yearly horoscopes.
Your Sun sign is determined by your birthday. If you were born on a day when the Sun changed signs, you may need to consult a personal natal chart because you may be one sign over the other. Because you can’t have two Sun signs, cusps don’t exist (despite pop culture magazines’ best efforts; Karen, stop trying to make them a thing!).
