Astrology is a very ancient discipline which dates back to old Babylon. The importance of planetary influence was known to our ancestors.

They observed the planetary movements and noted their influence on people’s lives and the world that surrounded them. They collected their observations in a discipline which they named astrology.

Astrology interprets the meaning of the planetary positions in a certain moment of time, like the moment of someone’s birth or an event. The positions are placed in a natal chart and then analyzed using various astrology techniques.

Astrology analyzes the placements of planets in different signs of the Zodiac as well as the aspects between the planets.

It also analyzes the placements of planets in the different houses of the natal chart. These placements show the areas where the person will most likely focus their attention or where most of the activities is likely to take place.

The aspects are also important. They are relationships between planets formed when the planets are at a certain angle of distance. The most significant are the exact aspects. They might be major and minor and can have beneficial or challenging nature.

Major aspects are the most important for astrology analysis. These aspects are conjunctions, trines, opposition, square, and trine.

Beneficial aspects are those which create harmonious relationships between the planets that form the aspect. They allow the energy and nature of the planet to express freely and enable the planets to cooperate.

If the aspects between the planets are predominately challenging in nature, the situation is different. In this case, the aspect blocks the energy of the planets and prevents them from expressing their best nature. It creates obstacles and stops manifestations of desires.

Trines are beneficial aspects and have a fortunate nature. They are considered the most fortunate of all aspects. They are formed when planets are at a distance of 120 degrees.

Trines create wonderful opportunities for success and achievement of goals. They help the person to accomplish what they desire.


Astrology also has a technique to analyze relationships and their potential. It can be used to analyze whether a relationship has a chance to stand the test of time or not. The technique astrology uses is called synastry.

Synastry determines compatibility between people and the possible issues they could experience.

Synastry usually uses the basic comparative analysis. It makes a comparison betwee the natal charts of two people to determine their compatibility. It calculates the aspects between the planets and their placements in the houses of the partner’s natal chart.

The houses where the partner’s planets are placed reveal the possible areas where this person will influence their partner.

The aspects between two natal charts are also very important. They determine the dynamics of the relationship and the possible direction it could take. Harmonious aspects between their planets usually indicate good compatibility of characters.

They often share the same interests and are willing to put in the effort to maintain the relationship.

They don’t allow issues to pile up and they resolve as they appear. When the aspects between the natal charts of two people are predominately inharmonious the situation is different.

This usually indicates lack of compatibility and disagreements between the partners.

They lack understanding and don’t have tolerance for their differences. They usually don’t want to put in the effort to maintain their relationship and allow issues to pile up.

Sometimes challenging aspects indicate conflicts and in worst cases violence. This relationship might drain the partner’s energy and is often not long lasting.
