Quick answer
An aspect is a set angle between two planets in your chart, and it shows how those two parts of you get along. The five major aspects are the conjunction (0 degrees, fused), sextile (60, easy teamwork), square (90, friction), trine (120, natural flow) and opposition (180, a tug of war). The closer the angle is to exact, the stronger it reads.
Key takeaways
- Aspects are angles between planets, and they describe which parts of you cooperate and which ones clash.
- The five major aspects are the conjunction, sextile, square, trine and opposition.
- An orb is how far an aspect is from exact, and tighter orbs read as stronger.
- Hard aspects are not bad; they create friction that often drives growth and chemistry.
Two people can both have Venus in Leo and still love in very different ways. One of the biggest reasons is aspects: the angles their Venus makes to other planets.
Planets and signs tell you what each part of you is like. Aspects tell you how those parts talk to each other. Some pairs cooperate. Some argue. Some are fused so tightly you cannot tell them apart. This guide explains the five major aspects in plain words, how orbs work, and how to read them when the question is love.
What is an aspect in astrology?
An aspect is a meaningful angle between two planets, measured around the 360 degree circle of the zodiac. It describes the relationship between the two drives those planets stand for.
Think of each planet as a person at a table. A conjunction seats them side by side. A square puts them at right angles, where they keep bumping elbows. An opposition seats them across from each other, looking straight at one another. The angle changes how the conversation goes.
Aspects are the lines you see crossing the center of a chart wheel. If you are new to charts, start with how to read your birth chart and come back here for the detail.
What are the five major aspects?
The five major aspects come from dividing the circle by 1, 2, 3, 4 and 6. Here they are in one table.
| Aspect | Angle | Tone | What it feels like | Pattern to watch |
|---|---|---|---|---|
| Conjunction | 0° | Fused | Two drives acting as one | Hard to see either one clearly |
| Sextile | 60° | Easy | An open door you have to walk through | Wasted if you never use it |
| Square | 90° | Tense | Friction that forces action | Reacting instead of choosing |
| Trine | 120° | Flowing | A natural talent | Taking it for granted |
| Opposition | 180° | Tense | A tug of war, often with other people | Projecting one side onto a partner |
Astrologers often group the sextile and trine as soft aspects and the square and opposition as hard aspects. The conjunction depends on which planets are involved. Hard does not mean bad and soft does not mean good. It is about how much friction the pair creates.
Conjunction (0 degrees)
The two planets sit in almost the same spot. Their meanings blend. Sun conjunct Venus, for example, makes love and identity feel like the same thing: being loved is part of feeling like yourself.
Sextile (60 degrees)
Usually two signs apart, in compatible elements (fire with air, earth with water). It shows an ability that works well once you put effort in. It rarely forces itself on you.
Square (90 degrees)
Three signs apart, usually in signs that share a modality but not an element. The square is where you feel pushed. Moon square Mars, for instance, can mean that hurt comes out as anger before you notice it was hurt.
Trine (120 degrees)
Four signs apart, usually in the same element. It flows. Moon trine Venus often gives an easy gift for tenderness.
Opposition (180 degrees)
Six signs apart, directly across the wheel. The two sides want different things and need balancing. Oppositions often show up through other people: you meet the other half of the pair in a partner.
What is an orb, and how tight does an aspect have to be?
An orb is the allowed distance from exact. Planets rarely sit at the perfect angle, so astrologers accept a range. A square between planets at 10 and 14 degrees of their signs has a 4 degree orb.
There is no single agreed orb table. Different books and programs use different limits. Wider orbs are usually allowed when the Sun or Moon is involved, because they are treated as the most important points.
Here are the orbs Venara uses, so you can see a concrete example of the rules:
- Conjunction and opposition: 7 degrees, or 8 when the Sun or Moon is involved.
- Square and trine: 6 degrees, or 7 with the Sun or Moon.
- Sextile: 4 degrees, or 5 with the Sun or Moon.
Within any orb, closer is stronger. A 1 degree square is felt much more than a 5 degree one.
One quirk to know about: aspects are measured in degrees, not signs. Venus at 29 degrees of Aries and Mars at 1 degree of Cancer are only 62 degrees apart, which counts as a sextile, even though Aries and Cancer are normally square signs. Astrologers call this an out-of-sign aspect. It usually reads a little more mixed than a clean one.
There are also minor aspects, such as the quincunx (150 degrees) and the semi-sextile (30 degrees). Some astrologers use them, many beginners skip them. The five major aspects carry most of the meaning, so learn those first.
What is the difference between applying and separating aspects?
An aspect is applying when the faster planet is still moving toward exact, and separating when it has already passed exact. In a birth chart, many astrologers read applying aspects as themes that build over your life and separating ones as themes that feel more familiar from early on.
This distinction matters more in timing work. When a planet moving through the sky today forms an aspect to a planet in your birth chart, that is called a transit, and applying transits describe a period that is building. Our guide to what transits are covers that side.
How do you read aspects for love?
Look at aspects between the four love points first: the Sun, Moon, Venus and Mars. Those pairs describe how affection, desire, emotional need and identity fit together inside you.
A few examples:
- Venus conjunct Mars. Affection and desire arrive together. Attraction tends to be obvious and quick.
- Venus square Mars. Real chemistry and real friction. You may be drawn to people who also frustrate you. The heat is a feature to steer, not a flaw.
- Moon trine Venus. Tenderness comes naturally, and you receive care easily too.
- Sun opposition Moon. What you want and what you need can point in different directions. A relationship has to make room for both.
Aspects between two people's charts work the same way. When your Venus squares your partner's Mars, you get friction and spark between you. That comparison is called synastry, and synastry explained walks through it. For the Venus and Mars pairing inside one chart, see Venus and Mars together.
Are some aspects good and others bad?
No aspect is simply good or bad. Soft aspects feel easy, and easy things can go unused. Hard aspects feel difficult, and difficult things often become strengths through effort.
A chart full of trines can describe someone talented who never feels pushed. A chart with several squares can describe someone restless who ends up building a lot. Neither is a verdict. Remember too that these readings are a symbolic tradition, not measured personality science. They are most useful as prompts: "Does this friction show up in my life? What do I do when it does?"
What should you do with your aspects?
Three practical steps:
- Find your tightest aspect. Look for the smallest orb in your aspect list. Write one sentence about how those two planets might interact. Then check it against a real week of your life.
- Look at your love aspects. Note any aspects between your Sun, Moon, Venus and Mars. These often explain why you want one thing and chase another.
- See them listed for you. If you want your aspects calculated with clear orbs, start your free reading. Every section of a Venara report lists the placements it was built from, so you can see which aspects shaped each paragraph.
Frequently asked questions
What is the strongest aspect in astrology?
The conjunction is usually treated as the strongest aspect, because the two planets sit almost on top of each other and their energies blend completely. After that, the square and the opposition are felt strongly because they create tension. In practice, the aspect with the smallest orb in your chart is often the one you notice most.
Are squares bad in a birth chart?
No. A square is a 90 degree angle that creates friction between two planets. Friction feels uncomfortable, but it also pushes you to act and adjust. Many people find their squares describe exactly where they have worked hardest and grown the most. Every aspect has a strength and a pattern to watch.
What is an orb in astrology?
An orb is the number of degrees an aspect is away from exact. If Venus is at 10 degrees and Mars at 13 degrees of signs that are square, the square has a 3 degree orb. Astrologers set a maximum orb for each aspect type. Tighter orbs are read as stronger and more noticeable.
What does a trine mean in astrology?
A trine is a 120 degree angle between two planets, usually in signs of the same element. It shows an easy flow between the two drives, often a natural talent. The pattern to watch is that trines can be taken for granted, because they work without effort and do not force you to develop them.
What is the difference between an applying and a separating aspect?
An applying aspect is one where the faster planet is still moving toward the exact angle. A separating aspect is one where it has already passed exact and is moving away. Many astrologers read applying aspects as building or still developing, and separating aspects as more settled or familiar.
