Since the trajectory of the Sun, when viewed from Earth, has a circular shape, we represent the zodiac as a circle. The circle is divided into sectors (zodiac signs), some of which are located opposite each other. Aries opposes Libra, Capricorn opposes Cancer, and sidereal Taurus is opposed by two constellations at once - Scorpio and Ophiuchus.
Since each zodiac sign has a ruler planet, the opposition of the signs generates a confrontation of the planets. For example, Mars (ruler of Aries) is the exact opposite of Chiron (ruler of Libra), and the Moon (ruler of Cancer) is the opposite of Saturn (ruler of Capricorn).
To clearly see the kinship and enmity of the signs, I made an infographic that reflects the actual planetary properties adapted to the sidereal zodiac. You can trace in which constellation the planet shows its strength and weakness, based on the traditional astrological concepts of domicile, exaltation, detriment and fall.
Many people associate astrology with the delusion that the stars and planets influence the events of our lives. You have probably heard a phrase like “if something goes wrong, then Mercury retrograde is to blame.” In fact, the planets don't affect us in any way. But, doing astrology, we adhere to the theory that the world is a single system, and everything is synchronized in it - Earthly processes and planetary cycles. Since the movement of the planets can be easily calculated for months ahead, then the events of these months can be tried to predict. The main gag is to interpret the calculation reliably. Because planets cycles are regularly repeated, but in different combinations. Here are some examples:
