Transits How It Works
1. Transit: The Cosmic Weather
A transit is the ongoing movement of a planet in the sky today, tracked as it passes through the zodiac and forms angles to your natal placements. Unlike your natal chart -- a fixed snapshot of the sky at your birth moment -- transits are real-time: they shift daily or weekly for fast-moving planets like Mercury, Venus, and Mars, coloring short-term mood and focus; slow outer planets like Saturn, Uranus, Neptune, and Pluto take years to cross a single sign, anchoring the sweeping, years-long chapters of a life. The cycle repeats: every planet will eventually return to its birth position (a "return" transit), and the slow planets revisit the same areas of your chart multiple times across your lifetime, each pass marking a new layer of the same theme.
2. Natal Placement: The Fixed Reference
Where a planet sat in your chart at the exact moment you were born -- the fixed reference point every transit is measured against. Your natal Sun, Moon, Mercury, Venus, Mars, Ascendant, and Midheaven don't move; they mark the psychological and life areas where transiting planets activate. When a transiting planet passes over your natal Sun, it spotlights your identity and core drives. When it forms a precise angle (an aspect, below) to your natal Saturn, it introduces friction that pushes you to restructure your boundaries and responsibilities.
3. Transiting Planets: Slow Movers Only
Not every planet is checked as a transiting body. We scan the slow-moving outer planets -- Jupiter, Saturn, Uranus, Neptune, Pluto -- along with the Moon's North Node and Chiron. Fast-moving personal planets like Mercury, Venus, and Mars shift positions so rapidly that checking them would generate hundreds of trivial events per year; focusing on the slow planets surfaces the meaningful developmental cycles that astrology actually tracks.
4. Natal Targets: Which Points Activate
Transits activate five personal planets and two personal points: your natal Sun, Moon, Mercury, Venus, Mars, Ascendant, and Midheaven. These seven placements represent your core identity, emotional nature, thinking, desire, action, rising sign, and career/public role -- the areas where transiting planets have the most visible impact on daily life. Placements in transits use the exact same ecliptic longitude as in your natal chart, so a transit-to-natal comparison is a direct angle measurement.
5. Aspects: The Angles That Matter
Transits do their work by forming precise angles to natal placements. We check five aspect angles, each with its own orb window (below): - **Conjunction (0°)** -- the transiting planet arrives at the exact degree of your natal placement, spotlighting that dimension of your chart intensely - **Opposition (180°)** -- the transiting planet sits directly across from your natal placement, activating its mirror or complement - **Square (90°)** -- friction and tension that demands adjustment or action - **Trine (120°)** -- natural, flowing support and ease - **Sextile (60°)** -- opportunity and cooperative potential These five are the working aspects for transits. A transiting Saturn conjunct your natal Sun, for instance, introduces a years-long cycle of clarifying and refining your identity and purpose.
6. Orb: Tighter Windows Than Natal
The orb is how many degrees off from the exact aspect angle the transiting planet actually is. A conjunction at 0.5 degrees off is far more potent than one at 2.9 degrees off, even though both technically qualify. Transits use tighter orbs than natal charts because they're events unfolding in real time, not fixed placements. Major aspects in transits (conjunction and opposition) are recognized within a 3-degree window; minor aspects (trine, sextile, square) within 2 degrees. This tightness ensures we flag only the most exact, high-impact moments.
7. Power Windows: When Multiple Hits Align
A power window is a day flagged as particularly significant, worth extra attention. Two conditions trigger it: either a slow-moving outer planet (Saturn, Uranus, Neptune, Pluto) forms an exact aspect to one of your three personal points (Sun, Moon, Ascendant) -- these heavy hits always matter -- or two or more transit events land on the same day, creating a pile-up of planetary activity. The Saturn Return (ages 29 and 58), the Uranus Opposition (the classic mid-life shift near 40), and Jupiter returns every twelve years are well-known examples of extended power-window periods. These windows are the hinges on which long-term life chapters turn.
