Now, let’s put it all together.
If you click here, there is an animation that illustrates both the orbits of an observer’s planet (Earth, the blue one) and a target planet (the one you’d look at, ex Mars, Jupiter, etc). Also, on the bottom, it shows both the sun and target planet’s apparent movement through the zodicial constellations.
Lastly, I present you with this image, which shows the movement of all the planets through the stars.
What astrology does in “natal charts” or “birth charts” is compiles the placements of all those planets, the sun, and the moon along the ecliptic. Then, assesses which constellation each is in. Finally, the interpretation of what each celestial body could mean when it’s in each of those constellations/signs.
Thus concludes this little lesson, I hope it helped. :D
We covered the Sun and Moon’s apparent movements, but that still leaves the other planets, doesn’t it?
Well, here is an animation that illustrates both the action and apparent movement of Mars.
To the left, you can see the actual orbits of the Earth and Mars around the Sun, and the arrows show where Mars appears to be in the Celestial sphere.
Well, let’s not forget that the celestial sphere is composed of stars, and constellations.
This image here, shows the constellations that lay along the ecliptic.
Remember back to your old Science classes, how you learned that all the planets revolved around the Sun? Do you recall being taught that there was a time before that, when people thought the solar system revolved around the Earth? Well, that’s when astrology started.
The basic concept is that surrounding the Earth is another sphere, on which lays all the stars. There were also theories that the Sun/planets were on separate varying sized spheres, but essentially it was accepted that they moved along the Celestial sphere along a line they called the ecliptic.

Also, time was dictated by the sun. As we all know, this is not perfect, hence the creation of Leap years. Back then, they assumed the celestial sphere was simply moving at a different pace. However, they also noticed that while after one day had passed (from midnight to midnight, assuming) the stars would be shifted slightly.
If you click here, there is an animation that illustrates the movement of the sun and moon in this concept.
This is how the sun appears to “move through the constellations.” Because from one 24 hour period, it isn’t quite in the same place it began in.
We’ve all flipped through magazines, or wandered through the internet, and found out that we have a “zodiac sign” based on our birthday.
Somehow that lead you here. Maybe you just wanted to see more about what that meant, or maybe you’re interested in your “birth chart” whatever that is. Maybe you’re interested in learning more about astrology.
Well, we know our sun signs based on our birth day. Then we found other websites where we plug in some stuff about our birth year, time, and city, and it gives us information about other planets and celestial objects. All of them saying they are “in” a sign.
Have you ever wondered why it is that way?
Well, as was posted a little bit ago, all of the “zodiac signs” originated from 12 constellations.
Why were those ones chosen?
Because those are the constellations the sun/planets appear to move through during the year.
In the next few posts, I’ll be showing you how this all works, to provide a better understanding of the basic mechanics of astrology.
