The 12 zodiac signs, with which many people are likely familiar today, were created during this Ancient Greek period. The signs of Aries (approximately March 21-April 19), Taurus (April 20-May 20), Gemini (May 21-June 20), Cancer (June 21-July 22), Leo (July 23-Aug. 22), Virgo (Aug. 23-Sept. 22), Libra (Sept. 23-Oct. 22), Scorpio (Oct. 23-Nov. 21), Sagittarius (Nov. 22-Dec. 21 These Western, or tropical, zodiac signs were named after constellations and paired with dates based on their apparent relationship to the sun’s position in the sky.
By 1500 BC, the Babylonians had divided the zodiac into 12 equal signs, with constellation names that were similar to those we know today, such as The Great Twins, The Lion, and The Scales, and these were later adopted into Greek divination. These 12 signs were popularized by the astronomer Ptolemy, author of the Tetrabiblos, which became a key work in the history of Western astrology.
“Ptolemy codified the idea that there were 12 signs of the zodiac that were 30 broad, and that the sun travelled through these signs on a regular basis throughout the year,” adds Odenwald. According to the Oxford English Dictionary, the word “zodiac” derives from the Greek, from a term for “sculpted animal figure,” and the sequence in which the signs are normally enumerated also stems from that time period.

What is the significance of the zodiac signs?
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 12 signs of the zodiac?
Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces are the 12 zodiac signs in order. Each zodiac sign has a symbol that dates back to Middle Ages Greek manuscripts. Let’s look at the zodiac symbols, constellations, and qualities in more detail.
Aries (March 21-April 19)
The ram is the constellation that represents Aries, the first of the twelve zodiac signs. You are adventurous, active, ambitious, and competitive if you were born under this sign. Aries are recognized for their agility and leadership abilities, as well as a tendency to be impetuous and blunt (due to the “fire” aspect).
Taurus (April 20-May 20)
Taurus is the second of the twelve zodiac signs, and the constellation Taurus represents it. You are dedicated, dependable, focused, and creative if you were born under this sign. Tauruses are noted for their intelligence, trustworthiness, and stubbornness (the sign is a bull, after all). Tauruses are notorious for questioning authority and seeking pleasure.
Gemini (May 21-June 20)
The constellation Gemini, which is made up of the Dioscurithe twins, Castor and Pollux, represents Gemini, the third of the twelve zodiac signs. You are active, expressive, intellectual, and playful if you were born under this sign. Geminis are recognized for their gregarious personalities and diverse interests, yet they have a (probably undeserved) reputation for being duplicitous.
Cancer (June 21-July 22)
The constellation Cancer, which is most typically pictured as a crab, represents Cancer, the fourth of the twelve zodiac signs. If you were born under this sign, you are brave, empathetic, protective, and perceptive. Cancers are noted for their tendency to be remote and passive-aggressive, as well as their caring nature.
Leo (July 23-August 22)
The lion is the constellation that represents Leo, the fifth of the twelve zodiac signs. You are vivacious, extroverted, and fiery if you were born under this sign. Leos are recognized for their warm personalities and great self-esteem, although they can be proud or jealous at times.
Virgo (August 23-September 22)
The virgin is the constellation that represents Virgo, the sixth of the twelve zodiac signs. You are practical, analytical, and sophisticated if you were born under this sign. Virgos are recognized for their generosity and meticulous attention to detail, yet they may also be introverted and have unrealistic expectations for themselves and their loved ones.
Libra (September 23-October 22)
The scales, the only inanimate constellation, represents Libra, the seventh of the twelve zodiac signs. You are thought to be balanced, social, and diplomatic if you were born under this sign. Libras are recognized for their selflessness and camaraderie, although they can be overly pragmatic and insecure at times.
Scorpio (October 23-November 21)
Scorpio is the eighth of the twelve zodiac signs, and it is symbolized by the scorpion constellation. You are loyal, resourceful, and dedicated if you were born under this sign. Scorpios are recognized for their boldness and pioneering spirit, but they may be abrasive and walled off to strangers.
Sagittarius (November 22-December 21)
The archer is the constellation that represents Sagittarius, the ninth of the twelve zodiac signs. If you were born under this sign, you are cheerful, self-reliant, and intellectual. Sagittariuses are noted for their magnetic qualities and generosity, yet they can also be arrogant and direct.
Capricorn (December 22-January 19)
Capricorn is the tenth of the twelve zodiac signs, and it is symbolized by the sea goat constellation. If you were born under this sign, you are patient, hardworking, and disciplined. Capricorns are recognized for their tenacity and fondness for boundaries and regulations, but they may be stubborn and too concerned with perfection.
Aquarius (January 20-February 18)
Aquarius is the eleventh of the twelve zodiac signs, and it is symbolized by the water carrier constellation. If you were born under this sign, you are thought to be creative, loyal, and unique. Aquariuses are recognized for their rebellious temperament and ingenuity, but they can be aloof and unyielding with loved ones.
Pisces (February 19-March 20)
Pisces is the last of the twelve zodiac signs, and it is symbolized by the fishes constellation. You are intuitive, artistic, and sympathetic if you were born under this sign. Pisces are famed for their empathy and artistic abilities, yet they can also be overly sensitive or delusional.
Who is the creator of the zodiac?
According to NASA, the Babylonians had already constructed a 12-month calendar based on the phases of the moon when they created the zodiac. Despite the fact that they identified 13 constellations that make up the zodiac, they decided to leave one out so that the zodiac signs would coincide better with their 12-month calendar.
But, before all of you Aries, Cancers, and Leos start making fun of your new Ophiuchus friends, keep in mind that the addition of this 13th constellation shifts every zodiac sign’s time frame slightly, which means that, while I’ve loved my life as a textbook Pisces, I discovered that I’m now an Aquarius after doing my research. (Gasp!)
Although 3,000 years old, this information reappeared this year when NASA disclosed scientific data regarding the Earth’s axis, which has moved and no longer points in the exact same direction as it previously did, affecting the amount of time each constellation is visible in the sky.
The astrology community (and Twitter) went crazy, and many ardent followers assumed NASA was involved “added a sign to the zodiac, causing havoc with the signs we’re all familiar with. That, however, is not the case. NASA omitted an astrological symbol from the design. They wrote a Tumblr blog entry about it “I’ve just done the math. If you want to point the finger, it should go to the ancient Babylonians for leaving Ophiuchus out of the picture in the first place.
Which zodiac sign has the most intelligence?
Aquarius is the zodiac sign with the highest intelligence. Uranus, the planet of invention, creativity, and expanded consciousness, rules them. As a result, this air sign does more than just process information and spit it back out: they evaluate, comprehend, and expand on it. “They’re creative, unconventional, and frequently ahead of their time,” Kovach adds. “They have a good understanding of how upcoming trends work and may have a picture of the future that others don’t.”
Do the signs of the zodiac have any significance?
It is the individuals, not the zodiac sign, who are responsible for developing connections, according to a Quora writer. All 12 zodiac signs have a positive sign linked with them, but you can’t forecast all of a person’s attributes or character just by glancing at their horoscopes. It is thought that couples with similar spiritual feelings are more likely to bond, whilst couples with incompatible zodiac signs are more likely to split up. This isn’t always the case, though.
What was the origin of Zodiacs?
The zodiac signs are a division of the ecliptic that dates back to Babylonian astronomy in the first millennium BC. Stars from earlier Babylonian star catalogues, such as the MUL.APIN catalogue, which was produced approximately 1000 BC, are used in the zodiac. Some constellations, such as Gemini “The Twins,” from MA.TAB.BA.GAL.GAL “The Great Twins,” and Cancer “The Crab,” from AL.LUL “The Crayfish,” can be traced even further back, to Bronze Age (First Babylonian dynasty) sources.
