Aspects of Western Astrology

Aspects form an important part of astrology. As we all know planets move in their defined orbits around the Sun. While doing so, they form various angular relationships with each other. These relationships are called Aspects. The prominent aspects are conjunction (0 degrees), opposition (180 degrees), trine (120 degrees) and square (90 degrees). These are formed as a result of splitting the circle (360 degrees) by very simple numbers like 1, 2, 3, and 4. Due to their relative position, when two planets form an aspect with each other, their power, energies and nature combine with each other. This combination may work together in conformity and peace or in tension and stress. For instance, if an angle of 90 degrees is formed between two angles, then they form a square which indicates that they are connected in a very powerful way.

Unfavourable Aspects also known as hard aspects

The hard aspects depict hurdles, obstruction, challenges and substances. They have the ability to hinder and handicap the smooth flow of events in one's life. But this does not mean lack of hard aspects is good. The absence of these unfavourable aspects can make the person's presence weak or thin. The various unfavourable aspects are: Semi-square (45 degrees), Square (90 Degrees), Opposition (180 Degrees).

The favourable aspects also known as Soft aspects

The soft aspects deliver comfort, serenity, and transparency in our lives. They are easy and simple to interpret and enable us to analyse the events in the areas where these aspects dominate. Also, abundance of Soft aspects make life boring, without any thrill and adventure thus lacking substance. The various favourable aspects are: Sextile (60 Degrees), Trine (120 Degrees).

The moon aspects

The Moon has great significance in astrology. The position of the Moon in one's Zodiac at the time of a person's birth is that particular person's Moon Sign. This position reveals a lot about the person's inner self. The Moon sign indicate about the emotional status and habits of a person. It gives the explanation for a person's behaviour and reveals the unconscious side of a personality. It is the Moon sign which explains why two people with the same Sun sign are different from each other. Since Moon sign relates to the deeper inner aspects of one's nature, the feelings, emotions, creativity and you intuition can be regulated by the Moon. Like the Moon expands and shrinks in the Sky, it affects the feelings within the person thus affecting the emotional status. In addition to this, the travelling of Moon through all the houses in the chart brings about change in mood. Moon takes 28 days to pass through all the houses of the chart. This means that it stays in each house for 2¼ days.

The Houses

There are 12 houses in the Zodiac or astrological chart. Each house represents an aspect of our lives such as love, career or family. The houses are very important in the interpretation of astrology. The Houses are equivalent to the signs of the Zodiac, but they're also dedicated to certain aspects of the person's life. One House is devoted to finances, another to health, for example. Because there are twelve houses but only ten planets each astrological chart will have two vacant houses. These vacant houses represent areas of the life that are unimportant in this life. It is believed that either you have been successful in that aspect of your life in another life or other aspects of life are in more immediate need of attention than those represented by the vacant houses.

The Signs

The Zodiac sun signs are the most common aspect of western astrology. There are twelve sun signs, based, roughly, on the months of the year. Each sun sign rules for approximately twenty eight days. Your Sun sign represents the sign of the Zodiac that the Sun was in at the time of your birth. The twelve signs of the Zodiac are well known to most people. They include Capricorn, Sagittarius, Aquarius, Scorpio, Gemini, Libra, Leo, and Aries, among others. The sun signs are most often used to create typical horoscopes.

Frequently Asked Questions

What are aspects in astrology?

Aspects are angular relationships between planets in a chart, such as conjunction (0 degrees), square (90), trine (120), and opposition (180). They describe how planetary energies combine or clash.

What is the difference between soft and hard aspects?

Soft aspects like trines and sextiles often flow with less friction. Hard aspects like squares and oppositions highlight tension, growth edges, and the need for conscious effort.

Do aspects matter in a birth chart?

Yes. Placements show what; aspects show how energies interact. A chart with strong squares can still be powerful when you understand the friction points.

Which aspects should beginners learn first?

Start with conjunction, opposition, square, and trine. They appear most often in charts and explain the majority of planetary chemistry in plain language.
