Planetary transits — how to read what's happening now
A planet moving today touches a sensitive point in your chart. It isn't a prediction — it's a process.
A birth chart photographs the sky at your birth. Once fixed, it never changes — it is your background map, for life. The planets, though, keep moving. And from time to time, one of them passes back exactly over a point in your natal chart.
That is what we call a transit. Not a prediction — a process. Here is how they work, which ones really count, and how to find your bearings in their tempo.
What a transit is
A transit is the passage of a current planet over a position in your natal chart. Today, Saturn is at 12° of Aries. If you have a natal planet at 12° Aries, Saturn is "transiting" it.
That passage activates the natal planet involved. Not by "causing" something, but by putting the ground of that planet under light. Saturn transiting your natal Moon activates your emotional ground — not by magically saddening you, but by surfacing the emotional matters you had been pushing away.
Not all transits are equal. A Mercury transit lasts two weeks and barely registers. A Saturn transit lasts twelve to eighteen months on the same point, in several passes (Saturn's retrograde motion means it crosses the same position three times). It is that duration that makes the difference: Mercury whispers, Saturn engraves.
We also distinguish transits to the angles (rising, lower sky, descendant, Midheaven). These are the most striking — when a heavy planet crosses one of your angles, it is almost always a threshold in your life.
Why some transits count more than others
Three factors set the weight of a transit.
The speed of the transiting planet. The slower the planet, the deeper the transit. The Moon transits every natal planet every twenty-eight days for a few hours — barely visible. Saturn takes thirty years to come full circle, so each transit lasts a good year. Uranus, Neptune, and Pluto are slower still: their transits can last two to five years.
The slow transits (Saturn, Uranus, Neptune, Pluto) are the ones to watch first. They structure the great periods of a life. Jupiter, in between, marks about a year and usually brings momentum or expansion.
The type of aspect formed. A conjunction (0°) is the most intense — the current planet is on the natal planet. An opposition (180°) marks tension, often external. A square (90°) marks a block to get past. A trine (120°) or sextile (60°) marks an easing current.
The natal planet touched. Not all are equivalent. A transit touching an angle (rising, Midheaven) or a luminary (Sun, Moon) is almost always more marking than a transit on a secondary planet far from the angles.
Applying or separating — the tempo
A transit is not lived the same way depending on whether it is approaching, exact, or moving away.
In the applying phase (the planet nearing the exact point), pressure builds. This is when questions start to surface, when things shift imperceptibly, when you sense "something." The closer to exact, the denser it gets.
At the exact point, the event is often crystallised. This is when you sign, you leave, you make the decision, you live the revealing incident. Not every transit produces a visible event — some stay inward — but the exact point is always a threshold.
In the separating phase (the planet moving away), it is integration. What played out crystallises and is digested. Often you understand in hindsight what happened — whereas at the exact point you are too far inside to have the distance.
And then there is retrogradation. Slow planets pass over the same point several times (on average three for Saturn): a direct applying pass, a retrograde pass, then a final direct pass. Each pass revisits the same subject from a slightly different angle. The subject returns — but it is yours to work differently.
Transiting Uranus in Gemini at 0°48' forms a square to the natal Sun in Pisces at 1°25' with an orb of 0.6° — applying, meaning the pressure is still building. It is the tightest transit in the chart right now, and it touches the natal Sun: not a peripheral planet, but the gravitational centre of the chart. You said you were living this period as a threshold. Uranus square Sun at 0.6° of applying orb is precisely the geometry of a threshold.
What this changes for you
Understanding transits means no longer enduring the sense that "everything happens at once" at certain times — and "nothing moves" at others. What plays out in your life has a tempo. Knowing that tempo lets you anticipate, align with the waves rather than fight them.
A transit reading does not predict what will happen to you. It tells you: here is the ground on which Saturn, Jupiter, Uranus, Neptune, and Pluto come to find you over the next two to three years, here is what those planets traditionally ask, and here is how to position yourself.
It is one of the most useful readings to have before an important decision (a life change, a long project, a commitment). And it is exactly what Astreïa offers in its "Transits" module.
