The angular relationship between a transiting planet and the planets or angular points of the natal horoscope is referred to as a transit. When the transiting planet creates an angle with the natal planet equal or equivalent to the angle already present at birth between the same planets, it is categorised as a recurring aspect . The aspect can be partial if the angular relationship is limited to the transiting planet and the natal one. It is defined as complete or total if the aspect that forms between the transiting planet and the natal planet is also present between the transiting planets. For instance, if a trine exists between the Sun and Jupiter in the natal horoscope, we have a partial recurring aspect when Jupiter or the Sun in transit forms a trine with the natal Sun or Jupiter. If the Sun and Jupiter, in transit, also form a trine with each other, we would speak of a total recurring aspect. It should be noted that even a similar or opposite aspect (such as a sextile and a square towards a trine) allows the transit to be interpreted as recurring.
We distinguish between different types of transit:
Simple isolated transit
The term ‘simple isolated transit’ refers to individual transiting planets passing through significant points of a natal horoscope. Typically, these transits exhibit strong influences only in specific circumstances. The transits of the semi-slow and slow planets, including Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto, tend to have more distinct effects than the transits of the Sun, Moon, Mercury, and Venus. The transit can trigger more intense effects if the natal planet is in a strong position, such as being the dominant planet in the birth chart. Additionally, when recurring aspects are formed between isolated transits, the importance of the transit itself is accentuated.
When a transiting planet occupies a strong position in the birth chart, its effect can be amplified. Additionally, the impact of the transit is heightened if the transiting planet is stationary at the point of formation of the aspect. In such cases, even fast planets are capable of exerting prolonged effects.
In the hierarchy of astrological aspects, the conjunction transit holds the most significant influence, with the opposition and square aspects following. It is important to note that the conjunction, being a neutral aspect, highlights an ambivalent disposition that requires thoroughly examining the planets involved and the harmonious or critical recurring aspects. For instance, the direct transit of Jupiter over the natal Sun is typically viewed as positive. However, there may be adverse effects if a critical natal aspect exists between the Sun and Jupiter.
Concerning the value that should be attributed to recurring aspects, it is generally accepted that a positive recurring aspect replaces, for the entire duration of the transit, a negative aspect that is present between the same planets of the native’s birth chart. Conversely, a negative recurring aspect accentuates negative predispositions. Concurrently, a harmonious recurring aspect reinforces the harmony already present in the natal aspect.
The interpretative meanings that can be attributed to a transit depend on the nature of the transiting and transited planet, as well as the type of aspect involved. The transiting planet is characterised by its nature, location in the natal horoscope at the time of aspect formation, and its significance in the natal chart. The transit effects are generally visible in the sector of the natal chart occupied by the transited planet. However, multiple factors must be considered when making an assessment. For instance, if natal Saturn is situated in the 6th house and transiting Saturn forms an aspect with the natal Sun in the 1st house (pertaining to physical appearance), health-related implications may arise. While the house through which the transiting planet traverses is significant, it is not as important as the other factors at play.
Simultaneous formation of transits on multiple points of the birth chart
The occurrence of simultaneous transits is a situation that exemplifies the average degree of complexity and interpretative diversity. The presence of transits at multiple points denotes a set of circumstances that culminates in the most pronounced transit, thereby expressing and activating the conditions that have accumulated. The critical or harmonic value of the accumulation is determined by the same principles discussed in the case of simple transits.
Accumulation of transits on a point of the natal horoscope
When a single planet is affected by multiple transits, paying attention to the meaning and position of the transited planet is crucial. Additionally, one must consider the previously stated regarding the isolated transit. The effect is even more pronounced if the natal planet is a part of the transiting configuration. For instance, when the transiting Sun and Saturn touch the natal Sun. Furthermore, an accumulation of fast planets can define a vital event, even without the intervention of a transit of slow planets.
Reciprocal transit refers to the crossing of aspects between the natal and transiting planets (e.g., transiting Jupiter forms an aspect to the natal Sun, and transiting Sun forms an aspect to natal Jupiter), which results in a pronounced effect that tends to manifest in the sector where the natal planet transited by the slow planet is located. The effect is particularly distinct when a recurring aspect accompanies the reciprocal transit, whether complete or partial. For instance, if there were an angular relationship between the Sun and Jupiter at birth, the effect of reciprocal transit would be more pronounced.
It is not uncommon for a planet in transit to form an aspect with a natal planet during its periodic retrogradation. This occurrence can result in three transits: the first in direct motion, the second in retrograde motion, and the third in direct motion again. From an interpretative perspective, two scenarios can be considered. The first scenario views the resulting event as a process consisting of an initial phase, a subsequent crisis, and a resolution or conclusion. While the first and last transits are relatively easy to connect with the event, the median transit is more challenging to define and relate to the contingent facts. The second scenario involves a single major event occurring at the time of the first contact, with subsequent connections having no effect. The event is repeated during successive transits only if it was not resolved during the first transit. While the first model seems to apply more profitably to harmonic transits, the second appears appropriate for critical or disharmonious transits.
If the beginning of a planetary retrogradation coincides with the formation of an aspect, a double transit takes place. Typically, this event happens when the transiting planet remains motionless in the position of aspect formation and subsequently undergoes retrogradation and returns to direct motion. In such cases, interpretation is based on the fact that the event lacks sufficient potency to express itself entirely until the circumstances that trigger its manifestation are reviewed.
 Not to be confused with planetary return, which occurs when the luminaries or planets return to the same natal position.
