Now that we've covered the planets, signs, and houses, it's time to explore how they interact. In astrology, the geometric angles between planets are called 'aspects'. You can think of them as conversations, creating a dynamic story within the birth chart.

An aspect isn't always exact to the degree. Astrologers use an 'orb', which is a small margin of a few degrees, to determine if an aspect is active. For example, if two planets are 92 degrees apart, they are still considered to be in a square aspect, which is exactly 90 degrees.

Aspects also have direction. An 'applying' aspect is when the faster-moving planet is approaching the exact angle of the aspect. This often feels like building anticipation. A 'separating' aspect is when the faster planet has passed the exact angle and is moving away, indicating the energy is integrating or resolving.
