Aspect is the geometric relationship between two planets in the horoscope chart. Aspects are important in analyzing a horoscope because they give the combined effect of the functions of the two planets involved. The major aspects between the planets are the conjunction, semi-sextile, sextile, square, trine, square, Quincuncx and opposition.
The semi-sextile, sextile, trine and conjunction are said to be good or favorable whereas the square, opposition and quincunx are taken to be not favorable.Aspects are the vital factors in the formation of ones character.
The Conjunction - The conjunction is formed when two planets are at approximately the same degree of the same sign or at an orb of not more than 8 degrees. In a conjunction, the energies of the two planets are combined, and the result is often a strengthening of both. Connjuction of Lords of 1, 4, 7 and 10th houses produces good effects. Conjunction of the trine Lords (5th and 9th houses) are always good irrespective of their location.A Moon-Venus conjunction is beneficial whereas a Saturn- Mars conjunction is said to be stressful.
The Semi-Sextile - This aspect is formed when two planets are 30 degrees apart with an orb of two degrees in either direction. This aspect is reckoned to be mildly favorable with the planets working well together.
The Sextile - Sextiles occur when two planets are approximately 60 degrees apart. This is the aspect of opportunity. It is the 3rd and the 11th house Hindu aspect. Initiatives can be taken during this aspect and it reinforces the weak points in life.It is a very beign aspect indicative of talent, confidence and popularity.
The Square - Squares occur when two planets are approximately 90 degrees apart. It is the 4th and the 10th house Hindu aspect. Square causes the friction and the hurdles that help us to grow and become productive.This is the most critical amd conflicting aspect. It gives disturbed, prejudiced or adverse conditions and circumstances accompanying it. It is a separative aspect and it turns the tide of fortune.
The Trine - A trine occurs when two planets are approximately 120 degrees apart. It is the 5th and the 9th house Hindu aspect. Trines bring about ease and comfort.This is a fortunate aspect for harmony, peace and does much to improve adverse aspects. When occuring between Sun and Moon it is more fortunate than any other aspect.
Sextile – 360 divided by 6. The sextile has less of the ease that the trine has, 6 is a Venus number it hasn’t got quite the established gravitas of trine, it’s the beginners benefic, the flowering rather than the fruit. Again we always look at the planets. Sextile is an aspect that occurs when planets or other points in a chart are about 60° apart. It's a stimulating aspect that indicates talents and opportunities. If planets are in a sextile aspect, they are in signs with compatible elements. These two planets are harmonious and blend easily.
The Opposition - The opposition occurs when two planets are about 180 degrees apart.It is the 7th house Hindu aspect. As the name implies, opposition are obstacles that must be resolved.This is a malefic aspect of perfect balance. It includes confrontation and partnership. It indicates change of circumstances. Oppositions can manifest as mood swings

An astrological aspect is an angle between two planets. The word aspect comes from the Latin aspicere and means look. An aspect connects two or more planets to each other so they have to deal with each other whether they like it or not. Aspects transfer information so act like a communication network between the planets. An aspect can nurture, diminish, modify or increase the function of the planet concerned depending on the quality of the aspect and its angle.
The interpretation of planetary aspects is essential for reading a horoscope to form a picture of a person’s character. However, individual aspects should not be considered in isolation. They usually provide disconnected and even contradictory information. Some negative and judgmental interpretations, if taken seriously, may inhibit personal development. Each aspect may only relate to a small part of your life. Astrological aspects are part of a whole interdependent structure. So it is critical to consider all of the aspects in a horoscope holistically, especially by looking for aspect patterns.
A conjunction occurs when two or more planets lie together. It is a zero degree (0°) angle. The quality of a conjunction depends on the planets or points involved. Basically, it corresponds to a combination of different components that are hard to differentiate. This often causes a mainly embryonic state and indicates latent talent that must first be developed.
A semi-sextile is a small green aspect of a 30° angle. It indicates a need to experience, learn, discuss, read, and be informed about new things. It brings the information necessary to think objectively and neutrally. It helps you think in small steps, adding one piece of information to another until the collected perceptions make sense. It works by providing information and by communicating and it reacts to external stimuli. It is easily influenced and often changes its opinion. Objectivity and indifference merge in the process.
A sextile is a blue aspect of a 60° angle. It corresponds to the Venus qualities of harmony-seeking and willingness to compromise. It is accepting, adaptable and able to attract and assimilate substance. There is usually a passive defense against the loss of a state of harmony and often a fear of conflict.
A square is a red aspect of a 90° angle. The nature of the square is energetic, fiery and dynamic. There is usually a deployment of strength or supply of energy, which nearly always causes an increased readiness for action and motivation. There is a lot of strength available for assertion and defense. But the square also generates conflict, friction, crises, stress and sometimes also a tendency to aggression.
A trine is a blue aspect of a 120° angle. It has a relaxed and harmonious effect. It is a material aspect that tends toward abundance, luxury and enjoyment and gives sensual pleasure. Sometimes it indicates perfectionism or obsessive behavior.
A quincunx is a long green aspect of a 150° angle. It is an aspect of karmic imbalance that can affect health. It causes insecurities on the one hand and on the other the urge to achieve an imagined future goal. Sometimes it is also called the “longing aspect”, or inconjunct. It often brings crises, uncertainty, and eventually the challenge of restricting oneself to a single goal, in which case it aids decision-making. It is called “the large thinking step” and, according to the planets or points involved, it causes a “Faustian struggle” with the truth.
An opposition is a red aspect of 180° angle. It is formed when two or more planets or points lie exactly opposite each other in the zodiac. The planetary principles involved often contradict each other, which is experienced as inner tension and often an energy blockage, stress, or postural rigidity. An opposition also generates inner strength and endurance, particularly relating to the subject of the axis. Sometimes there is an increased tendency for repression, in which lateral aspects are compensated.
The word orb comes from the Latin orbis and means radius. An aspect orb is a radius of influence of a few degrees on both sides of the aspect angle, within which the aspect is still effective. This varies according to the astrological importance of the planet and the aspect concerned.
The table below shows the suggested aspect orbs developed by Bruno Huber.  It was tested over a 30 year period at the Astrological Psychology Institute. More than a thousand active astrological consultants all over the world put the aspects in horoscopes to the test almost daily in personal consultation with their clients.
