Stationary Transits: How a Station Changes Transit Timing

← Back to Transits

A planet "stations" when it appears to stand still before turning retrograde or direct. If that turn happens close to a degree in your birth chart, people say the transit is stationary, and they usually mean that it lasts longer. This page checks how much longer, for seven moving bodies, by measuring how many days each one spent near a fixed degree and sorting those stays by how far away the nearest station was.

Two things this page is not. It is not about a planet that was stationary on the day you were born; that is stationary planets at birth, a natal condition. And it does not count exact hits; that is why a transit can hit one, three or five times. A station near your degree can mean more hits, fewer hits or the same number. What it changes reliably is the time spent nearby.

The findings in brief:

• A station within 1° of the point multiplied the time spent near it for the faster movers. Within the 1° band used here, a typical Mars passage with no station nearby lasted 3 days; with a station within 0.10° it lasted about 29. Jupiter went from 9 days to about 61, Uranus from 136 to about 207, Pluto from 202 to about 367.
• Closest is not always longest. Inside 1°, the three distance groups gave similar stays, and their order changed from mover to mover and between the two sets of test degrees. A station right on the point did not reliably beat one that turned half a degree away.
• A single hit can be a long transit. Roughly half of the Mars, Jupiter and Saturn events with a station within 0.10° had only one exact hit: the planet turned just short of the point, lingered, and crossed once later. For Uranus, single-hit events spent longer near the point (median 196 days) than three-hit events (158).
• For Neptune, a nearby station was the rule. Every complete Neptune event in the window had a station within 1° of the point.

Educational guide: Astrologist.com has no transit calculator, transit calendar or automated transit report; the free birth chart is natal only. The figures below come from an offline calculation made once for this article with the planetary routines behind the chart, not from a feature of the site, and none of them is computed for your chart. Dates after October 2026 are model projections.

The 1° band is a measuring stick, not an orb rule

To compare planets, the time "near the point" has to be measured the same way for all of them. This page uses a band of 1° either side of the degree, as a measurement convention only. It is not Astrologist.com doctrine about when a transit begins, ends or matters; astrologers use many different orbs, and the free chart's aspect orbs are a separate matter. A wider or narrower band would give longer or shorter stays, but the comparison between near-station and ordinary passages is what the band is for.

For every complete event (defined on the hit-count page) four things were measured:

1. Visits: each stretch of time the planet spent inside the band. A planet that enters, slips back out during a retrograde, and comes back in has two visits.
2. Total time in the band: the visits added together, in days.
3. Calendar span: from first entry to final exit, which also includes any weeks spent outside the band between visits. It is shown separately so that time outside the band is never counted as time inside.
4. Nearest station: the smallest distance between the point and any turn of the planet during that calendar span.

Events were then sorted into four groups by that nearest distance, fixed before any result was seen and with no overlaps: 0° to 0.10°, more than 0.10° to 0.25°, more than 0.25° to 1.00°, and more than 1° or no station in the band.

Method in short

• Movers: Mars, Jupiter, Saturn, Chiron, Uranus, Neptune and Pluto, using the chart's own routines (VSOP87B for Mars to Neptune, Meeus chapter 37 for Pluto, the daily Chiron table for Chiron), Tropical longitudes of date.
• Window: 1 January 1950 00:00 UT up to but not including 1 January 2050, the same for every mover. Stays that started before the window or were still running at its end were left out of the statistics and counted.
• Test points: 360 fixed degrees at the half degrees (0°30' Aries, 1°30' Aries and so on), through every lap. A second set on the whole degrees was run as a check.
• Tracking: one continuous longitude per planet, sampled every 3 hours for Mars and Jupiter and every 6 hours for the rest; band entries and exits solved to under a minute; turning points located for grouping and reported to the day.

Time spent in the band, by distance to the nearest station

Median days inside the 1° band, with the 10th to 90th percentile range and the number of events, on the half-degree test points.

Event totals with a complete stay in the band: Mars 18,773, Jupiter 2,982, Saturn 1,187, Chiron 687, Uranus 421, Neptune 212, Pluto 195 (two complete events per mover had a stay that ran past a window edge).

The same events measured by calendar span, first entry to final exit (median and 10th to 90th percentile, days):

The gap between the two tables is the point of measuring both. A Mars event with a station within 0.10° stretched over about five months of calendar time but spent only about a month of it inside the band. The rest was the planet travelling its retrograde loop well away from the degree.

What the tables show

The jump is between "station within 1°" and "no station nearby". For Mars, Jupiter and Uranus, every group with a station inside the band sits far above the last column, and for Pluto the few events without a nearby station had by far the shortest stays. Saturn is the exception that proves the mechanism: its last column mixes quick single passages (about 17 days) with triple runs whose loop sweeps through the band three times, so its median of 67 days is not far below the station groups.

Inside 1°, distance mattered much less. The three station groups overlap heavily. For Saturn on the half-degree points, and for Mars and Jupiter on the whole-degree check, the group with the station furthest from the point had a higher median than the closest group. The reason is the measuring band itself: when a planet turns 0.6° beyond the point, more of its slow turning period falls inside the band (the band reaches 1.6° back from the turn) than when it turns exactly on the point (the band reaches only 1° back). For most movers here, a station exactly on a natal degree was not the arrangement that kept the planet inside a 1° band the longest.

Chiron and Pluto spread widely. Their stations sit close together in longitude, and in some years two consecutive turns fall inside the band, so the stays split into a one-loop group and a two-loop group. That is why their percentile ranges are so wide.

Near-station events by number of hits

The right-hand column is why the number of exact hits is a poor guide to how long a planet stays close. Uranus single hits happen only in the narrow gaps between its loops, right beside a station that turns just short, so they are long, slow passages.

How often a station falls near the point

As an event-level figure: the share of complete events whose nearest station was within 0.25° of the point was 0.2% for Mars, 2.6% for Jupiter, 7.8% for Saturn, 12.5% for Chiron, 19.5% for Uranus, 43.4% for Neptune and 45.6% for Pluto. Slow movers turn near any given degree far more often, because their loops are packed closely along the zodiac.

The second set of test points changed some medians

The whole-degree grid was run with the same rules. The broad picture held: every station group still sat well above the "over 1° or none" group for Mars, Jupiter, Uranus and Pluto, and Neptune still had no events without a nearby station. But several medians inside 1° moved by more than the margin agreed in advance (5% and 3 days), so both are shown.

The groups inside 1° hold only a few dozen events each for most movers, and they mix one-loop and two-loop stays, so their medians are sensitive to exactly which degrees are tested. Chiron's calendar span for the 0.25° to 1.00° group moved most (558 to 312 days), because that group sits right on the boundary between the two kinds of stay. Read the station-group medians as approximate. The contrast with the last column is the robust result; the ranking inside 1° is not.

One chart: the Bristol birth

The illustration chart is the fictional Bristol birth from Uranus square Uranus, fixed in advance: 12 August 1970, 14:20 British time, Bristol (13:20 UT), natal Sun 19°24' Leo. Only events beginning after the birth and inside the window count. Of its 54 complete events from Mars to Uranus, only two had a station within 1° of the Sun degree.

Saturn, 2035 to 2036 (projection): one hit, a long stay. Saturn turned retrograde on 30 November 2035 at 19°15' Leo, about 10' short of the point (the over 0.10° to 0.25° group). It was inside the band from 31 October to 30 December 2035 without reaching the degree, slid back to a direct turn on 12 April 2036 at 12°19' Leo, came back into the band on 11 July 2036, crossed the point once on 19 July and left the band on 27 July. Total: 77 days inside the band over a calendar span of 270 days, with one exact hit. Bristol's other Saturn events: a single hit in August 1977 with 16 days inside the band, and a three-hit run in 2006 to 2007 with 88 days.

Mars, 2009 to 2010: three hits around a turn. Mars entered the band on 6 December 2009, crossed the point on 13 December, turned retrograde on 20 December at 19°42' Leo (17' beyond the point, the over 0.25° to 1.00° group), crossed back on 27 December and left on 3 January 2010. It came back for four days in May, with the final hit on 16 May. Total 32 to 33 days inside the band; Bristol's 39 single Mars hits each spent 3 to 4 days in it.

The Bristol Sun has no event in the closest group (within 0.10°) for any mover. So, as agreed in advance, the closest-group example for each mover is taken from the test grid instead: the complete event in that group whose station fell nearest the middle of the window (1 January 2000).

Supplementary examples (synthetic test degrees, not birth charts)

"Short" means the planet turned before reaching the degree; "beyond" that it crossed and then turned. Jupiter, Saturn and Chiron all show the one-hit pattern: the planet passed the degree once, went on, came back in retrograde and turned direct a few arc-minutes before reaching it again, so it lingered without a second crossing. For Neptune and Pluto the three hits come from a neighbouring loop; the turn nearest the degree did not add a crossing.

Reading it

Many astrologers treat a station near a natal point as a time of emphasis. The measurement supports a narrower, plainer statement: a station within about a degree keeps the planet near the point for weeks or months longer, and spreads the event over more calendar time. It does not show that a station makes a transit stronger, more important or more intense, and an exact station date is a geometry, not a turning point in a life. If you use a station as a reason to give a theme more time for reflection, that is your choice of reading. Nothing here predicts events, health, relationships or finances.

Precision and the outside check

• Arithmetic. Band entries, exits and hits were solved to under a minute inside each model; that is a numerical tolerance only. Days in the band are given to the whole day.
• Models. The chart's own routines, as listed above. The Chiron table is daily with straight-line interpolation, so Chiron's turns are only resolved to the day, and the table's 1920 to 2060 coverage contains the whole window.
• Repository tests. The project checks these routines against the Swiss Ephemeris at daily noon over 1919 to 2061 with a 0.05° position allowance and station-timing gates. Those are allowances, not error bars on the figures here.
• Swiss Ephemeris, for these events only. Every turning point within 3' of a half-degree test point (123 across the seven movers, including the Jupiter, Saturn and Pluto examples above) fell on the same side of the point in Swiss as in the chart's routine, so no distance group would change. Swiss provides no figure on this page.

Checking a station against your own chart

1. Note the natal degree from the free birth chart.
2. In a Tropical ephemeris, find the retrograde and direct turns of the moving planet around the time it reaches that degree, and how far each turn falls from your degree.
3. If a turn falls within about a degree, expect the planet to stay close longer than an ordinary pass, often much longer, whether or not it adds hits. Count visits and calendar span separately.
4. Give dates to the day and record the source; a turn within a few arc-minutes of your degree is where sources can disagree.
