One of the foundational components of astrology is that of planetary aspects. They are the relationship that binds planets and zodiac signs. They dictate how planets and zodiac signs interact, and the dynamics that exist between them.
While zodiac signs only make up one piece of the puzzle when it comes to astrology, it is often the most popular. There is something quite fun about learning all the zodiac signs and their characteristics, especially when it comes to pointing out characteristics about yourself of those that are close to you.
