If you searched astrology aspects, this is your complete reference. Aspects are the angular relationships between planets in your birth chart — the way two planets “talk” to each other across the zodiac. They reveal the inner conversations that shape your personality. Below: the 5 major aspects, the 6 minor aspects, full symbols chart, cheat sheet with degrees and orbs, and how to actually read aspects in your own chart.
In astrology, an aspect is the angular distance between two planets in a birth chart, measured in degrees. Aspects describe how two planetary energies interact — harmoniously, with friction, with intensity, or with awkward adjustment. There are five major aspects (conjunction, sextile, square, trine, opposition) and several minor aspects (quincunx, semi-sextile, semi-square, sesquiquadrate, quintile, bi-quintile).
Imagine your birth chart as a circle of 360 degrees. Each of your ten planets sits at a specific degree somewhere on that circle. The aspects are the measured distances between any two planets — and certain specific distances (0°, 60°, 90°, 120°, 180°, etc.) create meaningful relationships. The signs describe the “how” of planetary expression. The houses describe the “where.” The aspects describe the inner conversations between planets — which energies blend smoothly, which ones grind against each other, and which ones force you to grow.

Note: orbs (tolerance) vary by tradition. Modern Western astrology typically uses wider orbs for major aspects, tighter orbs for minor. Hellenistic and Vedic traditions use tighter orbs across the board.
The five major (Ptolemaic) aspects are the backbone of chart reading. They describe the most powerful planetary conversations:
Two planets occupy the same degree (or within 8-10° of each other). Energies merge completely — neither planet operates independently any more. The strongest of all aspects. Can be intense, harmonious, or volatile depending on the planets involved.
Example: Sun conjunct Venus = beauty fused with identity; the person looks attractive and finds aesthetic expression central to who they are.
Two planets 60° apart. A gentle, supportive aspect. Energies cooperate but require conscious effort to activate. Not as automatic as a trine; not as forced as a square. Often called the "opportunity" aspect.
Example: Mars sextile Jupiter = available courage and luck; the person can take bold action when they choose to, but it does not happen passively.
Two planets 90° apart. A challenging, productive aspect. Energies clash in a way that forces development — square aspects build character because they cannot be ignored. The hardest aspect, and arguably the most growth-producing.
Example: Sun square Saturn = identity clashes with discipline; the person must work harder than peers but builds extraordinary persistence over time.
Two planets 120° apart. The most harmonious aspect. Energies flow together effortlessly. Trines describe innate gifts — talents that come so easily the person may take them for granted. Often underused because no friction forces engagement.
Example: Moon trine Jupiter = natural emotional optimism; the person bounces back from setbacks without strategy, and others find them comforting.
Two planets 180° apart — across the chart from each other. Energies pull in opposite directions, creating tension that demands integration. Often expressed through relationships (the qualities you reject appear in your partners until you integrate them).
Example: Venus opposite Mars = polarized love and assertion; the person attracts intense partners who embody the side of love they have not yet developed in themselves.
The minor aspects in astrology are subtler than the major five but they add crucial nuance to chart reading. Most beginners ignore them; experienced astrologers find them indispensable. The six most commonly used minor aspects:
Two planets 30° apart. A subtle, often unnoticed aspect. Creates minor adjustments and uncomfortable awareness without forcing major action. Often felt as a low-grade itch you cannot quite locate.
Ex: Mercury semi-sextile Venus = subtle blending of communication and beauty; words come out aesthetically pleasing without conscious effort.
Two planets 45° apart. A minor irritating aspect. Less intense than a square but creates persistent low-level friction. Often described as the aspect that nags rather than confronts.
Ex: Sun semi-square Mars = persistent low-level frustration with self-assertion; the person fidgets but rarely explodes.
Two planets 72° apart. A creative, gifted aspect. Quintiles describe unique creative talents — the kind of skill that appears almost magical to others. Often found in the charts of artists, inventors, and unique thinkers.
Ex: Mercury quintile Neptune = poetic mind; the person sees connections between ideas in ways that feel mystical to others.
Two planets 135° apart. A minor stressful aspect, sometimes called sesquisquare. Creates agitation that builds over time. Less acute than a square but persistent and cumulative.
Ex: Moon sesquiquadrate Saturn = chronic emotional restriction; the person feels weighed down emotionally without dramatic crisis.
Two planets 144° apart. A creative gift aspect, similar to quintile but expressed more publicly. Often found in artists whose creative work reaches large audiences. Less common than quintile.
Ex: Sun bi-quintile Uranus = unconventional creative identity; the person is naturally artistic in unexpected, original ways.
Two planets 150° apart, also called inconjunct. A famously uncomfortable aspect. The two planets share neither sign element (fire/earth/air/water) nor modality (cardinal/fixed/mutable), so they cannot find common ground. Often experienced as chronic awkwardness in the area.
Ex: Sun quincunx Mars = identity and drive that never quite align; the person has to work consciously to get their actions to match what they actually want.
The standard astrology aspects symbols used in chart software and traditional texts:
Reading aspects in a natal chart follows a four-step protocol:
Modern astrologers often forget this distinction, but traditional astrology weighs it heavily:
In a natal chart, applying aspects describe energies still in motion in your life. Separating aspects describe energies you have already integrated (or failed to integrate) and now carry as background.
A useful shorthand modern astrologers use:
The most resilient charts have a balanced mix of both types. Pure soft-aspect charts can be lazy; pure hard-aspect charts can be exhausted.
Sometimes multiple planets form a recognisable geometric pattern in the chart. The most common patterns:

Open Birth Chart Reader →The five major (Ptolemaic) aspects are: conjunction (0°), sextile (60°), square (90°), trine (120°), and opposition (180°). They form the backbone of chart interpretation.
Minor aspects are subtler planetary angles beyond the major five. The most commonly used are semi-sextile (30°), semi-square (45°), quintile (72°), sesquiquadrate (135°), bi-quintile (144°), and quincunx (150°). They add nuance to chart reading.
There is no single most important aspect — importance depends on which planets are involved and what is happening in the chart overall. That said, the Sun-Moon aspect is foundational because it describes the relationship between conscious identity and emotional core. Conjunctions are typically the strongest single aspect type.
No. Hard aspects (squares, oppositions, quincunxes) create friction that forces growth. People with many hard aspects tend to develop extraordinary strengths because life refuses to let them coast. Easy charts are not necessarily lucky charts.
An orb is the tolerance band around the exact aspect angle. A trine is exactly 120°, but a trine within 7° (so 113-127°) still counts. The closer to exact, the stronger the aspect. Different traditions use different orb sizes.

An applying aspect is one where the faster-moving planet is approaching exact aspect — energy is building. A separating aspect is one where the faster planet has already passed exact — energy is dissipating. Applying aspects are typically more powerful in their immediate effects.
A trine is a 120° aspect between two planets — one of the most harmonious aspects. Trines describe innate gifts and natural talents that flow easily. They are considered the most beneficial aspect alongside sextiles.
