Astrology is a study of planetary influence on people and the world. This is a very old discipline; according to the discovered records, it dates back to the ancient Babylonians.

Astrology analyzes natal charts of people or events to discover information about them. The natal chart is a chart of the sky in certain moment. Astrologers analyze the planets in signs but also the houses of the natal chart. They also analyze the aspects between different planets in the natal chart.

The meanings of planets placed in different signs of the Zodiac, especially personal planets, such as Sun, Moon, Venus, Mercury or Mars, are very important for astrology analysis, especially for determining someone’s character traits.

Also, planets placed in different houses of the natal chart give insight about the areas that the person will most likely be interested in and where the most of the activities will take place.

The aspects between the planets give an insight about the personality traits and the possible choices this person will make during their lifetime.

They represent certain angles formed between the planets which carry a specific meaning. They can be harmonious in nature or have a challenging nature.

Also, aspects can be minor and major. Major aspects have more significance and are used in every astrology analysis. The minor aspects can be significant too, especially when the angles between the planets are exact.

Harmonious aspects create new opportunities and balance. They stimulate the planets to express their best nature.

The planets connected with harmonious aspects are inspired to cooperate. These aspects allow the person achieve their goals without putting in much effort.

Challenging aspects are different; they create blocks in planetary energy and cause the planets to express the worst in their nature. They prevent the person from achieving their goals or put blocks and obstacles while they are trying to achieve them.

These aspects often cause conflicts and in worst cases aggression and violence.

The trine aspect is considered a fortunate one. Many astrologers consider it the most favorable of all aspects. This aspect helps the person get what they desire without much effort. They create opportunities for success and make it easy.


Astrology has a special technique which analyses relationships and their potential; it is called synastry.

Synastry compares the natal charts of two people to determine whether their characters are compatible or not. Synastry is based on the idea that people are like moving natal charts. When they encounter one another, their natal charts do the same.

Synastry determines the aspects between the planets in the birth charts of two people as well as the houses occupied by the partner’s planets. These houses show the areas of life where the other partner will mostly affect the person owner of the natal chart.

The aspects are also very important because they show whether there is genuine interest and attraction between the people.

If there are mainly harmonious aspects between the charts of two people this usually indicates that their natures are compatible. There is desire to be together and fight for the relationship.

They accept each other’s differences and are willing to make compromises without hesitance. They get along well and usually have similar interests.

When the aspects between two natal charts are mostly challenging, this is usually a sign of lack of compatibility between two sides. There is often not enough will to fight for the relationship.

These two aren’t tolerant to each other’s differences and they don’t want to adapt to that.

In many cases, both partners fight for dominance and right to be the leader in the relationship instead an equal partner. Sometimes, this is a relationship filled with violence and conflicts. Often these relationships are short-lived.

There are also situations where synastry analysis shows lack of aspects or significant aspects between two natal charts. That is usually a sign of lack of interest and compatibility between these two. Often this relationship doesn’t start at all.

Mercury – Basic Traits

The planet Mercury is tiny, and is considered the smallest in the Solar system. Before Mercury, Pluto was the smallest planet. Since Pluto lost that status, Mercury took its place. This planet is the closest to the Sun. It moves fast and it orbits the Sun in around 88 days.

Mercury was the ancient Roman god of travel and trade. Mercury was the messenger and the trickster.

In astrology, Mercury is also the ruler of commerce, traveling, short-distance travel, communication, luck, education, news, thinking, trickery, deceit, lies, nervousness, surroundings, neighborhood, siblings, etc.

This planet’s placement in the natal chart reveals the manner we usually express our thoughts.

Especially people that are under the influenced by Mercury are quick witted and intelligent.

These people are also very communicative and sociable. They enjoy being surrounded by many people. They are also very curious and enjoy gaining knowledge.

Mercury people love to be informed and love all kinds of news, but sometimes Mercury people love listening to the latest gossip and gossiping themselves. They often choose an occupation where they can be in contact with people.

Mercury in challenging aspects, gives the person negative traits of Mercury, such as nervousness, proneness to deception and lies, manipulation, etc.

Sometimes this is an indication that the person is prone to being lied to and manipulated by others.

Mercury people can be very manipulative because they easily notice other people’s weaknesses and know how to make the most of them.

These people are often not emotional, or at least not very emotional. It might be said that they have a rational and practical approach to things, especially the matters of the heart. These people enjoy listening to other people talking but they also love talking themselves. 

Mars – Basic Traits

The planet Mars is also a tiny planet. It is the second smallest, following Mercury. This planet is small, but has a scary reputation. It rules aggression and violence, and makes people under its influence prone to these traits.

The surface of Mars is covered with iron dioxide, which is red. That is why Mars is often called “red planet”. It is similar to Earth in some ways, and that is why some people believe that life will be possible on Mars in the future. Some people even believe that once life existed there.

This is a planet of aggression, conflicts, brutality, disasters, destruction, and other negative things.

Especially when Mars has challenging aspects in the natal chart, it can have destructive influence on people. It is the ruler of brutality, war, impatience, violence, military, disagreements, scars, wounds, weapons, intolerance, etc.

A well-placed Mars gives the person determination, decisiveness, strong willpower, endurance, confidence, leadership skills, powerful personality, energy, etc.

These people are focused on their goals and determined to succeed.
