The circle is then divided into 12 equal slices, like a clock, each measuring 30º. (Galactic Geometry 101: 12 x 30º=360º or a full circle.) Each of those 12 slices represents the part of the sky ruled by one of the 12 zodiac signs.  

​Has my zodiac sign changed as the constellations have shifted? 
In a word, no. In ancient times the constellations did line up with the zodiac wheel, which is how each of the 12 wedges got its name. But as NASA reported (correctly), the constellations have shifted over time. In Western astrology—the system we use, which stems from the stargazing of the Babylonians and Greeks—the constellations were simply placeholders.  

There are other (equally fascinating) "sidereal" systems, such as Vedic astrology, that track the planets in relation to the fixed stars that form constellations. In fact, a novice's "discovery" of this is how that 2016 rumor got started that your zodiac sign changed—and that there was a thirteenth sign called Ophiucus. As much as we'd love to add another celestial squad member to the mix (and one so closely named to Ophira, at that) we are also happy to report that you are still the same sign as you've been reading since you began reading your ‘scope. 

What does it mean that a planet is "in a sign"? 
As we mentioned, your natal chart is like a screenshot of the sky at your exact moment of birth. While most people know their Sun sign—which is the one you've been reading about on Astrostyle—you may have been surprised to learn that you also have a moon sign, Venus sign, Neptune sign, and so on. Each one is like a specialized GPS, guiding you towards the love that your soul desires and needs.  

As you take your first breath, each planet will be orbiting through one of the twelve slices of the zodiac wheel.  When we "freeze frame" their motion in your chart, we can see exactly where they land.

Just as no two people are exactly the same—not even identical twins, trust us—the probability of all the planets lining up in the same formation twice is so rare that it's almost an impossibility!  So unique is the birth chart, in fact, that only someone born at the same minute in the same time zone as you will share your chart.  

​As identical twins born four minutes apart, we have a few, albeit tiny, differences in our chart. Most notably: Tali, who was born first, has a rising sign of 9º37" Capricorn and Ophi's clocks in at 10º37". If you don't know your birth time, don't worry! Most planets move so slowly that it's easy to figure out what sign they are stationed in. The Ascendant/rising sign, which changes signs every two hours may have to be "intuited"—and the moon sign, which shifts every 2.5 days may also be tricky to determine. (As you learn the zodiac, it may become obvious to you, however which sign it is.) The rest of the chart provides an incredibly rich landscape, giving you plenty to explore and obsess over!    

​What the zodiac signs tell us about ourselves 
The 12 zodiac signs progress from Aries to Pisces, paralleling the evolution of feelings from immediate to eternal. Each sign represents a different piece of the love journey. When a planet lands in this sign in your natal chart, it takes on the role of that particular zodiac sign—and will color your approach to amour.
