Aspects for Beginners: Five Conversations Between Planets

Last lesson, you read three layers: “Venus (actor) in Libra (style) in the 7th house (stage).” Yet ten planets do not perform isolated monologues. Some stand close; others face each other across the wheel. Their angles describe cooperation, tension, or independent paths.

These angles are aspects. Meet the five most common, find them in charts, and complete a four-layer sentence. You will then have the four building blocks needed before asking AI questions.

Aspects are angles between planets

Think of the chart as a 360-degree circle. Angular separation creates aspects. The five major aspects relate roughly to sign spacing, since each sign spans 30 degrees:

Read both planets’ degrees, calculate separation, and find the closest standard angle. The hover-to-read skill applies here too.

Harmony and tension, rather than good and bad

Sextiles and trines are harmonious aspects, with easier flow. Squares and oppositions are tense aspects, with friction or competing pulls. A conjunction depends on the planets involved and can feel harmonious or tense.

Do not equate these with good and bad. A trine can remain undeveloped because it feels effortless; a square can drive growth and strength. Major achievements may emerge from a chart’s strongest tension. Aspects describe how energy interacts, rather than score your life.

Instead of asking whether a tense aspect is good, ask about its gift and what needs practice. Try this with AI:

Orbs: how close counts?

Planets rarely sit exactly 90.0 degrees apart. An aspect can remain valid within a few degrees; this allowance is its orb. astro.how’s default orbs are 7° for conjunctions and oppositions, 6° for trines and squares, and 4° for sextiles. Adjust them in chart Settings.

Remember two points:

• Smaller differences make tighter aspects, usually given more emphasis. A square at 90.5° is tighter than one at 95°.
• Orbs are conventions, not physical laws. Astrologers use different values, so approach borderline aspects five or six degrees away more lightly.

For details, including why wider orbs are often used for the Sun and Moon, see Aspects.

Find aspect lines in a chart

Colored lines in the center connect aspect pairs, with colors varying by aspect type. Fictional Chen Yutong’s chart contains examples of all five:

Translate these lines into everyday language:

• Sun conjunct Mercury: Core identity and thinking blend; ideas feel part of who she is, and speech reflects identity.
• Sun sextile Pluto: An opportunity to use depth and focus for self-realization, requiring active use.
• Moon square Mars: Feelings prompt action; impulses and emotions can clash, offering something to practice.
• Venus trine Saturn: A natural grasp of commitment and boundaries in relationships, suggesting reliability and steadiness.
• Sun opposite Moon: Born around a full Moon, she may feel pulled between her desired self and private security needs, requiring balance.

Two of these correspond to visible astronomical patterns. Sun–Mercury conjunctions are common because Mercury orbits inside Earth’s orbit and always appears near the Sun:

The Sun opposite the Moon is a full Moon: Earth lies between them and the Moon’s illuminated face points toward us. Drag time and observe the phase when their separation reaches 180 degrees:

Try another chart. Lines show that an aspect exists; degrees confirm its type and tightness.

Four layers: planet × sign × house × aspect

You now have all four elements for a complete sentence:

The Moon (emotional needs) in Cancer (sensitive, protective style), in the 4th house (home and foundations), squares Saturn (tension with duty and rules).

This is the complete astrological sentence introduced in lesson one. Follow the same order: planetary energy, sign style, house stage, then aspect partner and interaction. Each layer adds precision and moves beyond a single zodiac label.

Aspects describe interaction, rather than a fixed script. Moon square Saturn points to tension to work with, rather than inevitable family trouble. Your response remains your choice.

You can now read four layers. The next three lessons return to AI-assisted learning. Begin with How to Ask Meaningful Astrological Questions.
