It makes much more sense to conclude that the stars that make up a constellation are close together, and all cast a similar energy on to the earth.
It gets very convoluted when you consider other suns (stars) in other solar systems that can also see some of our Zodiac signs. Other suns/stars can also have one of our signs in it’s own ecliptic path, so one sign can theoretically be in two Zodiacs! This is very likely given the number of other suns.
What world gets more influence? The one with life? Are the heavens biased now?
