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 relative to the stars on any given day say, June 21 wanders a very small amount each year.
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.
Why was the killer known as the Zodiac Killer?
The Zodiac Killer was the moniker of an unidentified serial killer who terrorized Northern California in the late 1960s. The case has been dubbed “America’s most famous unsolved murder case,” having become a part of popular culture and prompting amateur investigators to try to solve it.
Between December 1968 and October 1969, the Zodiac murdered five people in the San Francisco Bay Area, in rural, urban, and suburban settings. His known attacks took place in Benicia, Vallejo, unincorporated Napa County, and the city of San Francisco proper, where he targeted young couples and a lone male cab driver. Two of his intended victims made it out alive. The Zodiac claimed responsibility for the murders of 37 people, and he’s been linked to a number of additional cold cases, some in Southern California and others beyond the state.
The Zodiac came up with the term in a series of taunting letters and cards he sent to local media, threatening murder sprees and bombs if they didn’t print them. Cryptograms, or ciphers, were included in some of the letters, in which the killer claimed to be gathering his victims as slaves for the hereafter. Two of his four ciphers have yet to be cracked, and one took 51 years to crack. While various speculations have been proposed as to the identity of the killer, Arthur Leigh Allen, a former elementary school teacher and convicted sex offender who died in 1992, was the only suspect ever publicly recognized by authorities.
Despite the fact that the Zodiac stopped communicating in writing around 1974, the peculiar character of the case piqued international interest, which has persisted throughout the years. The case was deemed “inactive” by the San Francisco Police Department in April 2004, although it was reopened before March 2007. The investigation is still ongoing in Vallejo, as well as Napa and Solano counties. Since 1969, the California Department of Justice has had an open case file on the Zodiac murders.
What does it mean to be a Leo?
Because Leo has come, the red carpet should be rolled out. The lion represents Leo, and these fiery fire signs are the celestial jungle’s kings and queens. They’re ecstatic to be a part of the royal family: Leos love to be in the spotlight and celebrate themselves. They are vivacious, dramatic, and passionate. These lions are natural leaders who appreciate building artistically and creatively inspired friendships and romances. Leos aren’t afraid to become involved in drama-filled romances that are excellent for the tabloids. (In fact, they could like them.) After all, every Leo considers themselves to be a celebrity. Luxurious dinners, exclusive parties, and sumptuous designer clothes never get old for these astrological divas.

What is the total number of zodiac signs?
Each of the zodiac’s 12 astrological signs is said to occupy 1/12 (or 30) of its vast circle. These symbols no longer match to the astrological constellations where the Sun can be found.
