The Language of the Planets
An introduction to aspects — the conversations between the planets
Astrology
About this class — full description
Adventures in Aspects: The Conversations Between the Planets. Every birth chart tells a story, but aspects reveal how the characters interact.
You can know what every planet means, understand every zodiac sign, and recognize every house, and still miss one of the most important parts of chart interpretation. Aspects are what turn individual placements into a living, interconnected system. They show how different parts of the psyche communicate, cooperate, challenge one another, and evolve over time.
This introductory class lays the foundation. Before we explore conjunctions, squares, trines, oppositions, sextiles and more in future classes, we first learn what aspects actually are, how they are measured, and why they are so central to reading a chart. Rather than memorizing isolated keywords, you'll begin recognizing aspects as relationships between planetary archetypes.
Tonight we cover
- What an aspect is and why it matters
- How aspects are measured using degrees
- Orbs, and why exact aspects are emphasized
- Applying versus separating aspects
- Major and minor aspects
- Hard aspects, soft aspects, and why neither is automatically "good" or "bad"
- How aspects modify planets, signs and houses
- Why two people with similar placements can live remarkably different lives
- How to begin hearing the conversation happening across a whole chart
By the end of this class you'll have a framework that makes every future chart you read richer, deeper and more connected. Welcome to your next adventure.
Where the series goes next
Each class focuses on a different aspect or aspect family, gradually building your ability to synthesize an entire chart instead of interpreting placements one at a time.

Aspects
& Transits
The planets are always talking to each other. Aspects are the angles they talk across. Transits are what happens when today's sky joins the conversation with your chart.

Tonight's route
Two hours, two ideas
- An aspect is the angle between two planets. Five of them do almost all the work.
- Orb is how much slack we allow. Tight orb, loud aspect.
- Applying or separating — is it building, or is it over?
- A transit is a planet moving in the sky right now, making an aspect to a planet in your chart.
- We read tonight's real sky, then read it against a real birth chart.
What you'll leave with
The ability to look at any chart and say, out loud, one true sentence about it: "This planet is squaring that one, and it's still building."
No memorising. Every number on the live slides is calculated on this page from orbital elements — same maths an ephemeris uses, no internet needed.
Idea one
An aspect is a distance
Lay the zodiac flat: 360 degrees, a full circle. Every planet sits at one degree of it.
Take any two planets and measure the shorter way around between them. That number — 0, 60, 90, 120, 180 — is the aspect. That's the whole trick.
Distance is the message. Planets close together blend. Planets facing each other pull apart. Planets a third of the circle apart get along easily.
Try it: Sun at 15° Leo and Saturn at 15° Aries are 120° apart. That's a trine.
The five that matter
The aspect arcade
Two of these feel like friction, two feel like ease, and the conjunction is whatever the two planets make of each other. Friction is not bad — it's where the movement comes from.
Idea two
Orb: how close is close enough
A square isn't only a square at exactly 90°. 87° still counts. That 3° of slack is the orb.
The tighter the orb, the louder the aspect. An aspect within 1° is often the single loudest thing in a chart. At 7° you'd barely notice it.
Orbs we'll use tonight — these are conventional, not sacred:
| Aspect | Angle | Orb |
|---|---|---|
| Conjunction | 0° | 8° |
| Opposition | 180° | 8° |
| Trine | 120° | 7° |
| Square | 90° | 7° |
| Sextile | 60° | 5° |
Hear the difference
Drag the orb and watch the aspect get louder or vanish.
—
Loudness bar = how close to exact. Full bar means the aspect is perfecting right now.
Idea three
Applying or separating
Planets move at different speeds. So an aspect is either closing in or walking away.
Applying — the faster planet is still approaching the exact angle. The event hasn't happened yet. This is the one to watch.
Separating — exact already passed. You're reading the aftermath, not the build-up.
Same two planets, same 3° orb, completely different story. Astrologers who skip this step end up predicting things that already happened.
Tonight, live
Real aspects in the sky right now, sorted by how tight they are.

Field test one
The sky over us right now
Rx = retrograde: moving backwards through the zodiac from where we stand. Speed is degrees per day — that's what makes the Moon's aspects last hours and Pluto's last years.
Field test two
Read one chart together
Birth data
No birth time? Leave it — everything except the Ascendant and the Moon's exact degree still holds.
Idea four
A transit is a visitor
Your birth chart never moves. It's a photograph of one instant, and it stays that way for life.
The sky, meanwhile, keeps going. When a planet moving overhead today reaches an angle to a planet frozen in your chart, that's a transit aspect.
Nothing new is happening in the sky — Saturn doesn't know you exist. What's happening is a meeting: a moving planet arrives at an angle to a fixed point of yours.
Always name it in that order: transiting planet, aspect, natal planet. "Transiting Saturn square natal Sun."
The one distinction beginners miss
Natal aspect: two planets in your birth chart. Permanent. It describes how you're built.
Transit aspect: a sky planet to a natal planet. Temporary. It describes what's being asked of you this season.
You can have a natal Sun–Saturn square your whole life and a transiting Saturn square your Sun for nine months. They rhyme, but they aren't the same event.
How long does it last
Speed is the whole story
A transit's meaning is mostly a function of how slow the visitor is. Numbers below are calculated live from tonight's actual planetary motion.
Slow planets retrograde back over the same degree, so a Saturn or Pluto transit usually hits three times: forward, back, forward again. That's why those years feel like one long argument you keep resuming.
The method
Reading one in four moves
- Who's visiting? The transiting planet sets the theme — Saturn tests, Jupiter expands, Uranus disrupts.
- Who's being visited? The natal planet sets the department — Sun is identity, Moon is home and mood, Venus is money and love.
- What's the angle? Conjunction fuses, square and opposition force a choice, trine and sextile open a door.
- Applying or separating, and how tight? This tells you when. Everything else tells you what.
Say it as one sentence
Transiting Saturn is square my natal Sun, applying, orb 2° —
"— so a test of who I say I am is building, and it perfects in about three weeks."
That sentence is a complete reading. Everything else is elaboration.

The whole night on one card
Angles
| Aspect | ° | Feels like |
|---|---|---|
| Conjunction ☌ | 0 | fusion — they act as one |
| Sextile ⚹ | 60 | an open door you must walk through |
| Square □ | 90 | friction that forces a decision |
| Trine △ | 120 | ease, often unnoticed |
| Opposition ☍ | 180 | a tug-of-war, usually with a person |
Homework, if you want it
Cast your own chart on the field-test slide. Find the single tightest transit to it. Write one sentence in the format we practised, then look at it again in a month.

Houses — where all of this is happening. Bring your birth time.
Positions here are calculated on this page from orbital elements — accurate to a small fraction of a degree, which is far tighter than any orb we used tonight.
