How to Understand Aspects in Astrology

Natal Chart Aspects

A natal chart or birth chart is a view of the sky from the exact place and the exact time of a person’s birth. Personality, emotions, and priorities can be observed through astrological aspects between the placement of planets in the natal chart.

The Sun sign is the constellation the Sun is in at the exact time of birth. The Moon sign is the Zodiac sign the Moon is in at the exact time of birth. The Rising sign or Ascendant is the Zodiac sign on the eastern horizon at the exact time of birth. Add 12 houses and 10-11 astrological planets to the mix, all representing different areas of life, and the beginning of an individual personality can be seen.

The Aspects are how all of the above relate to each other. Positive and negative, weak and dominant, aspects can skew the original belief of astrological representation. For example, if there is a conjunction including Venus and the Moon in Aries, it will strengthen the need for love and beauty, feeding on the energy of Mars, Aries’ natural ruler.


A Conjunction is the most powerful aspect. When a natal chart shows two or more astrological planets within 10 degrees of each other, the significance of the planets is combined. When a Conjunction appears, you can expect a double amount of energy from both astrological planets’ influences. Such as, the previous example with Venus and the Moon; love (Venus) and emotions (Moon) are doubly displayed.


A Sextile is the opportunity aspect. When a natal chart shows two or more astrological planets near 60 degrees of each other, there is a small possibility for opportunity in the areas the planets represent. This aspect is positive in nature, however, not very dominant. In fact, many other influences in the chart may override any of its contributions.

A Trine is Just Like it Sounds...



If two or more astrological planets are near 120 degrees apart, they create a Trine. This could be a major influence on harmony and communication concerning the areas the planets represent. The Trine is a great aspect to have. It helps to ease any differences between the two planets. This aspect is a peaceful aspect. Too many Trines is a person’s natal chart can cause them to be weak in character since they won’t experience the normal amount of hard knocks life dishes out.


The Square is a negative aspect causing one to learn a lesson by challenge and difficulty. Once again, if two or more astrological planets are near 90 degrees of each other, it may prove a bit of difficulty in the areas the planets represent. It could possibly cause a much needed change, and if one is aware of this in the birth chart, it can be dealt with. A square often indicates internal conflict.


An Opposition in a natal chart occurs when two or more astrological planets are near 120 degrees apart. This aspect is known as the second most influential aspect. When an Opposition appears in a birth chart, you can expect exactly what it’s named for; obstacles, and unresolved issues.

According to Edgar Cayce:

Aspects: the readings diverge rather drastically from textbook astrology. Aspects are seldom mentioned or given significance (in the readings).

Thus we find that the sojourns about the earth, during the interims between earthly sojourns, are called the astrological aspects (2144-1).

Traditional aspects between planets in the birth chart give little or no clue to the most important planets which will exert the most influence as indicated by the readings. In a study in 150 children’s readings it is more likely that there will be no orthodox astrological aspects between any of them.

Cayce was concerned with the lives of the soul in other dimensions.

My pleasure, girishpuri. Its important to let my readers know that I do not use astrology to predict the future, but as a tool to get to know people better. This hobby does't control my life. Anyway, I also want my readers to know that there is so much more to someone than only what their sun sign represents.

Thanks for your comment!
