 Whilst learning tropical astrology, many years ago, I first came across the concept of sidereal astrology, at that time I had so much new knowledge to explore within the vast topic of astrology I stayed with the Tropical system. Being a person who lives rurally, gardens, spends a lot of time in and with nature, including the night sky and the stars, seeing, for example, the Full Moon in Leo at 15 degrees in my America ephemeris, in my social media feed from my favorite astrologers, and looking physically with the naked eye at this Full Moon in Leo, I was actually looking at a full moon in the zodiac constellation of Cancer, confirmed by my night sky app, and the visible stars of the constellation.

After a decade of this discourse I decided to fully take up the natural rhythm of sidereal astrology. I do not dismiss the tropical system, it is just a preference, but there is truth for me in what I see is what I get!

When I adjusted to the thinking that I may be a Piscean not an Aries, I actually found that I could stand in this truth, even though I have a Sun Mars (Aries ruler) conjunction, anyone who knows me well understands that the Pisces is a much more suitable fit! In my Tropical Sun Mars in Aries chart, I have Mercury, Saturn, Chiron in Pisces. My Cancer Moon / Ascendant did not shift sign only degree, from 27 to 2 degrees.



Both forms of astrology contain signs named after constellations. The two systems were identical around 2,000 years ago, but drifted apart over the centuries, as the Tropical once was based on the constellations. Around 2000 years ago the Ancient Greeks (some say it was the ancient Babylonians, some say 3,000 years ago see below) began their year with the Spring Equinox, as the reference point, they then divide the ecliptic into 12 equal segments. Each of the Signs of the Zodiac was associated with the type of qualities and energy that were experienced during the corresponding time of the year. The foundation of the interpretations of the Signs was seasonal.

But as the fixed stars do move over time this is called the precession of the equinoxes. The movement is 1 degree every 72 years, which means for the tropical zodiac by following the seasonal vernal equinox, fixed point of 0 degrees Aries, the Tropical zodiac signs have moved approximately 24 degrees forward in following the fixed 0 degrees of Aries every vernal equinox. This is why you maybe an Aries in mainstream tropical astrology but looking directly up at the sky when you were born the Sun would have been in Pisces (given degree – if you were a late Aries in approximately the last 3 days your most likely to stay an Aries). Sidereal astrology takes into account this movement of the equinoxes, in Vedic astrology it’s called the ayanamsas (meaning movement component) (1) The sidereal zodiac is based on the actual constellations and their movement. Vedic astrologers have always used the sidereal system.
To recap, the tropical zodiac is set to the seasons of the Earth, not the visible sky. The sidereal is set to the visible constellations in the sky.
Horoscopes that you may follow in the newspaper, magazines, and your favorite social media platforms are based on the mainstream Tropical Astrology, it is called “tropical” because of its relationship to the latitudes on earth called the tropics. (2) Sidereal means Star.

Yes, Constellations are groups of fixed stars, named and associated with a story or myth. From NSW Australia one can see the Southern Cross, kite shaped configuration that features on the national flag. Others are Orion, The Big Dipper. (3)

The Zodiac Signs / Constellations refers to the different names for the Signs, signs are 30-degree units of measurement of the arc along the ecliptic, dividing the ecliptic into twelve. The Signs of the Zodiac are named after twelve of the Constellations that intersect the ecliptic. The Ecliptic is the Great Circle that describes Sun’s path around the Earth, it is really the orbit of the Earth around the Sun.

In James Grebey’s article “NASA: We Didn’t Change Your Zodiac Sign, Astrology Isn’t Real” on the Richard Dawings foundation for Reason and Science website, states; “86 percent of all people are actually born under a different zodiac sign,  and there are actually 13 astrological signs instead of 12”. Approximately NASA says, “3,000 years ago, the ancient Babylonians divided the Zodiac into an even 12 pieces. Each division was represented by the constellation that the sun would appear to pass through at differing points of the year as the Earth orbited around the sun”. “NASA says, The Babylonians cheated a bit. The sun didn’t actually pass consistently for a month, but varied, through each constellation”. The article states that the “Babylonians knew about the 13th constellation Ophiuchus, there was a thirteenth constellation, but apparently it did not get included as it would not have lined up with their calendar”.

Is the Zodiac accurate, according to NASA? NASA, study’s astronomy, not astrology,” “We didn’t change any zodiac signs, we just did the math.” NASA explains that the former is a science that intelligent people devote their lives to, and the latter is hooey”. “Astrology is something else,” NASA says. “It’s not science”. The article claims that “no one has shown that astrology can be used to predict the future or describe what people are like based on their birth dates.” (4)


According to Kari Paul, author, and researcher of “Why millennials are ditching religion for  astrology”, in these tumultuous times, the 18-30 demographic is reaching for the stars.

A Brooklyn-based producer, Coco Layne, on meeting someone new these days, the first question to arise in conversation isn’t “Where do you live?” or “What do you do?” but “What’s your sign?” “So many millennials read their horoscopes every day and believe them, “says Layne. So, are zodiac signs real? According to Layne, “It is a good reference point to identify and place people in the world.” (5)

According to the article, in recent years, interest in spirituality has been booming to the plummet of interest in religion, especially among millennials. A study from Pew Research Centre found, that many Americans now believe it is not necessary to believe in God to have good morals. The percentage of people between the ages of 18 and 29 who “never doubt existence of God” fell from 81% in 2007 to 67% in 2012. (5)

Are zodiac signs real? More than half of young adults in the U.S. believe astrology is a science.  “For a generation that grew up in a world of big industry, environmental destruction, large and oppressive governments, and toxic social structures, all of which seem too big to change, astrology can be incredibly attractive.” (5)

 “There’s no actual scientific proof to the actual existence of God and despite scientific research that has actually taken place, see The scientific study, “The Astrology File, Scientific Proof of the Link between Star Signs and Human Behavior” authored by Gunter Sachs (1977 The Guernsey press) astrology, are zodiac signs real, has been debunked by numerous academic studies.


Banu Guler, co-founder of artificial intelligence powered astrology app Co—Star said the lack of structure in the field is exactly what drives young, educated professionals to invest their time and money in the practice. “It’s very different from the way we usually work and live and date, where everything is hyper-mediated and rational,” she said. “There is a belief vacuum: we go from work to a bar to dinner and a date, with no semblance of meaning. Astrology is a way out of it, a way of putting yourself in the context of thousands of years of history and the universe.” (5)



Sarah Wells in her article “Ancient Wisdom – Sacred Alignment and the Constellation of Orion” says “For at least ten thousand years, human beings have been plotting the movement of the stars, studying the heavens, constructing calendars, and erecting monuments to track the procession of the constellations and heavenly bodies across the night sky”. “Many ancient cultures shared the belief that we came from the stars. Perhaps this is why so much time, effort, and energy has been put into the study of the celestial bodies from ancient times right up through today”.

“Several constellations and stars, such as Orion, have played an important role in ancient mysteries and mythology surrounding the celestial origins of our species. In the places where these legends emerge, we find structures, like the pyramids of Giza and Teotihuacan, Mexico, that correlate with the position of these stars and constellations in the sky”. (6) As well as places like Stonehenge in the UK.


“The Pleiades star cluster is thought to be seven young women, the Miyay Miyay (for the Greeks it is the “Seven Sisters”).  For various reasons, they ended up in the sky, where their parents in the Snowy Mountains could see them.  They were loved by some young men, the Birray Birray, who chased them, and they eventually ended up in the sky, as well, as the three stars that make up the Belt of Orion”. (7)


For the Kamilaroi and Euahlayi peoples of Australia, the Warambul, (Milky Way) meaning watercourse or river, the place where everything once was, until the Universe was turned upside down and everything ended up on Earth.  Many of the creation beings are still to be found in the Warambul, and many objects and stories have mirror places on Earth.  Behind the Milky Way is Bulimah, the sky camp, where persons go after their life on Earth (7).


The Greek word for zodiac is zōdiakos, from Latin zodiacus meaning circle of animals. The term zodiac is used to describe the circle of twelve celestial longitude divisions, centered upon the ecliptic – the path of the sun.  “From the earliest of times, the zodiac has been universally used to predict or reflect characteristics of personality, whether from the Chinese, Mesopotamian, Indus Valley, Egyptian or any other culture, echoing the ancient philosophy ‘As above – so below’… what we today call astrology”. Ancient Greek records show that they inherited their knowledge of the heavens primarily from the Mesopotamians, who inherited their knowledge from the Sumerians. And there is evidence of the constellations in art or culture from before this time. It has been proposed that the images at Lascaux and other nearby Paleolithic sites show artifacts of the constellations. (8)

Is the Zodiac real? I’ll leave it open to you 😊
