Key takeaways
What are aspects in astrology?
Aspects are the angles between planets in a birth chart. They describe how different parts of you interact.
If planets are characters in your inner world, aspects describe the conversations between those characters. Some conversations are easy. Some are tense. Some are intense and impossible to ignore.
Aspects add depth because they show how placements work together, not just what each placement means alone.
Conjunction: blended energy
A conjunction happens when two planets are close together. Their energies blend and become strongly connected.
For example, Moon conjunct Venus may blend emotions with love, beauty, and affection. Mercury conjunct Mars may blend communication with speed, directness, and intensity.
Conjunctions can feel powerful because the planets are operating as a team, even if the combination is not always simple.
Trines and sextiles: supportive flow
A trine is usually considered a natural flow between planets. It can show gifts, ease, and qualities that come naturally.
A sextile is supportive too, but it often works best when you choose to use it. It can feel like an opportunity or helpful connection.
These aspects are not automatically perfect. They simply show energy that may be easier to access than more tense aspects.
Squares and oppositions: growth through tension
A square can feel like friction between two parts of you. It often pushes growth because ignoring it becomes uncomfortable.
An opposition can feel like a tug-of-war between two needs. The goal is not to choose one side forever, but to learn balance.
Tense aspects are not bad. They often describe motivation, complexity, and the parts of life that teach you strength.
What is an orb?
An orb is the amount of distance between an exact aspect and the actual angle in the chart.
For example, a square is exact at 90 degrees. If two planets are 92 degrees apart, the orb is 2 degrees.
The smaller the orb, the more exact and noticeable the aspect may feel. Beginners do not need to obsess over orbs, but they are helpful for understanding strength.
