Every Planet Gives You the Same Number of Transits — the Moon's Last Seven Hours and Pluto's Last Three Years
Most transit calculator output looks the same: a stack of rows sorted by orb, tightest at the top. Take a chart born on 14 March 1987. On 23 August 2026 it had ten active transits at a two-degree orb. Sorted by orb, the top four were Mars opposite natal Neptune at 9 arcminutes, the Sun opposite natal Mercury at 19, the Moon conjunct natal Neptune at 21, and Mercury trine natal Uranus at 31. Those four contacts last six days, four days, eight hours and two days respectively.
Fifth and sixth on that list, at 49 arcminutes and one degree exactly, sat Pluto sextile natal Jupiter and Neptune conjunct natal Jupiter. Those two run for 3.7 years and 2.8 years. An orb sort had buried both of them under an eight-hour Moon contact. That is not a rounding error. It is what happens when you rank by the wrong number.
Every Planet Hands You Exactly One Tenth of the List
Here is the thing nobody says out loud about transit lists. I generated 500 birth charts spread across 1945 to 2008, sampled each of them at 60 moments over three years, and counted every aspect inside a two-degree orb — 30,000 chart-moments, about 268,000 rows. The Moon supplied 10.0% of them. Pluto supplied 10.1%. Mercury 9.9%. Every one of the ten bodies landed between 9.9% and 10.3%.
That balance is not astrology, it is arithmetic. Each transiting body travels the whole 360° of the zodiac, so each one passes each of your eighty aspect points equally often. Ten bodies, ten equal tenths. The typical chart carries 8.9 active transits at two degrees, nine at the median, thirteen at the ninetieth percentile — and the largest I saw was 25 at once.
So your list is, structurally, one tenth Moon and one tenth Pluto. The Moon's tenth is gone in seven hours. Pluto's tenth runs for three years and nine months. Same number of rows, a factor of about 4,500 in how long they occupy your life. Sorting that by orb tells you which row happens to be nearest exact this afternoon and nothing whatsoever about which one matters.
Sort by How Long It Lasts, Not How Close It Is
The fix is not a table of planet weights copied out of a textbook. It is measurable. For every transiting body I solved for the two orb edges — the moment it enters and the moment it finally leaves — across all 360 possible target degrees, and took the median.
| Transiting body | Median time in a 1° orb | Exact hits, average | Share that perfect more than once |
|---|---|---|---|
| Moon | 3.6 hours | 1.00 | 0% |
| Mercury | 1.2 days | 1.23 | 12% |
| Venus | 1.6 days | 1.06 | 3% |
| Sun | 2.0 days | 1.00 | 0% |
| Mars | 2.9 days | 1.08 | 4% |
| Jupiter | 9.2 days | 1.60 | 30% |
| Saturn | 9.1 months | 2.07 | 54% |
| Uranus | 10.9 months | 2.88 | 94% |
| Neptune | 21.8 months | 3.49 | 100% |
| Pluto | 2.7 years | 4.11 | 100% |
Read the Mercury row twice, because it is the strangest one. Mercury's median contact is a day and a bit — but its ninetieth percentile is 44 days. One Mercury transit in eight catches a retrograde and turns from an afternoon into a six-week serial. That is the same mechanism behind the three Mercury retrograde windows each year, seen from your chart rather than from the sky. Venus does the same thing on a longer fuse, which is why a natal Venus placement can sit in one sign for 126 days instead of the usual 25.
The calculator above builds its ranking from exactly this, except it measures your own contact rather than using the median. The scale is anchored so 100 is Pluto exactly conjunct your natal Sun, and closeness only ever shuffles a row among its neighbours. It never lets a two-day transit climb over a two-year one.
Watch One Transit Cross the Same Degree Three Times
Go back to that 1987 chart and take the row an orb sort put sixth: Neptune conjunct natal Jupiter. Neptune entered a two-degree orb of that degree in February 2026 and does not leave until late 2028. Inside that window it goes exact three separate times — 19 April 2026, 30 September 2026, and 19 February 2027.
The three dates are one transit, not three. Neptune moves forward, stations, retrogrades back over the same degree, stations again, and comes through a third time. The first pass introduces the theme, the retrograde pass is where it gets argued with, and the third is usually the one people remember as the event. This is the same three-pass structure that gives a Saturn return three exact dates instead of one, and it is why an outer-planet transit cannot honestly be reported as a date.
How often does that happen? For Neptune and Pluto, essentially always — every contact I measured perfected at least twice, and Pluto averaged 4.11 exact hits with a maximum of seven. For Saturn it is a coin flip at 54%. For Jupiter it drops to 30%, and for the Sun and Moon it never happens at all, because neither ever moves backwards.
Applying and Separating Are Not Two Halves of the Same Thing
A transit is applying while the orb is still closing and separating once it has passed exact. Most tools print the word and leave it there, which makes it sound like a fifty-fifty split of the transit's life. It is not, and the asymmetry is the useful part.
The applying half is where the pressure builds and nothing has happened yet — the stretch people describe afterwards as "I could feel it coming." The separating half is where you deal with what did happen. For a fast transit the distinction is academic; the whole thing is over in a day either way. For Pluto, applying and separating can each run eighteen months, and treating them as the same state is how people conclude a transit "did nothing" when they were simply still inside the run-up.
There is a third state the calculator flags separately, and it is the one worth watching: stationary. When a slow planet parks within a few arcminutes a day of your natal degree, it can hold the same orb for weeks. Those are the stretches that feel like the transit stopped moving, because from where you are standing it has.
Everyone Born in Your Year Has This One
About 8.3% of the rows in any transit list are one outer planet aspecting another outer planet — Pluto square natal Uranus, Neptune trine natal Pluto, and so on. They look impressive. They are also the least personal thing in the report.
Uranus takes 84 years to circle the zodiac, Neptune 165, Pluto 248. Anyone born within a year or two of you has natal Uranus, Neptune and Pluto within a couple of degrees of yours, so when transiting Pluto squares your natal Uranus it is squaring the natal Uranus of several million people simultaneously. It describes a cohort. It does not describe you. The calculator keeps those rows but cuts their weight to 35% and labels them, because deleting them would be dishonest and ranking them highly would be worse.
The corollary is the useful bit: at a two-degree orb, 88% of the time you have at least one Uranus, Neptune or Pluto transit running somewhere in your chart, and 95% of the time at least one Saturn-or-slower contact. A heavy transit is not a rare visitation. The rare thing is a stretch with none.
Why Pluto Takes Twice as Long in Taurus as in Scorpio
This one surprised me enough that I re-ran it. Pluto's median contact at a one-degree orb is 21.2 months when the natal planet is in Scorpio, and 3.77 years when it is in Taurus — a factor of 2.1 for the identical aspect.
The cause is not astrological at all. Pluto's orbit is badly eccentric, and its distance from the Sun swings between about 30 and 49 astronomical units. Perihelion falls at roughly 14° Scorpio and aphelion at 14° Taurus, so Pluto is sprinting through the Scorpio end of the zodiac and crawling through the Taurus end. If your natal Sun is in Taurus, a Pluto transit to it is genuinely a longer chapter of your life than the same transit would be for a Scorpio Sun.
Run the same measurement on Neptune and it is flat: 21.7 months in Aries, 21.9 in Libra, nothing in between worth mentioning. Neptune's orbit is nearly circular, so every sign gets the same dose. Two planets, two completely different answers to "how long does this last" — which is precisely why a fixed table of durations is not good enough and the tool solves each contact individually.
Four Ways a Transit List Gets Misread
Reading the tightest orb as the biggest event. Covered above, but it is worth naming as a habit rather than a one-off. If a row is at 4 arcminutes and lasts two days, its tightness is a coincidence of when you loaded the page.
Treating the exact date as the day it happens. For Saturn and slower, the exact date is the midpoint of a months-long stretch, and the visible event frequently lands nearer an orb edge or a station than the exact hit. Give a slow transit its window, not its date.
Counting a triple as three separate transits. Neptune conjunct your Jupiter three times in eleven months is one contact with three peaks. Logged as three, it looks like the same theme keeps recurring, which turns a single chapter into an apparent pattern.
Chasing a transit to a natal Moon you do not actually have. Without a birth time your natal Moon is only known to within about thirteen degrees, so any aspect to it is a guess. This calculator drops those rows rather than printing them; if you want the Moon in play, the moon sign calculator shows how far the position can drift across a single birthday.
When Not to Reach for Transits at All
Transits are a timing technique and they answer "when" far better than "what." If the question is what a placement means in your chart at all, a transit list is the wrong instrument — that is natal work, and the guide to how aspects and orbs actually work is a better starting point than any moving-planet report.
They are also the wrong instrument for anything house-based. Which area of life a transit lights up depends on your houses, and houses need your birth time and birth city to within a few minutes and a few miles. This page deliberately does not ask for either, because the aspect angles it reports do not need them and pretending otherwise would make the whole output look more precise than it is.
And they are worth putting down entirely when the honest answer is that nothing much is happening. About one chart in seventy has no transit at all within a one-degree orb on a given day — 1.5% of the 48,000 chart-days I checked. Widen to two degrees and it collapses to one in 2,400, which is itself worth knowing: the feeling that something is always going on is mostly a statement about your orb setting. Some weeks the sky is simply not talking about you, and a technique that can say so is more trustworthy than one that always finds something.
