The zodiac is a celestial coordinate system used in astrology, which divides the sky into twelve equal sections, each represented by a specific sign. These twelve signs, collectively known as the zodiac signs, correspond to distinct time periods throughout the year, as the Earth orbits the Sun. Each sign is associated with particular personality traits, preferences, and characteristics that are believed to influence a person's behavior, emotions, and relationships. Derived from ancient observations, the zodiac signs are named after constellations and are categorized into four elemental groups: fire (Aries, Leo, and Sagittarius), earth (Taurus, Virgo, and Capricorn), air (Gemini, Libra, and Aquarius), and water (Cancer, Scorpio, and Pisces). In astrology, the placement of the Sun in a specific zodiac sign at the time of a person's birth is considered their Sun sign, which is thought to reflect their core personality and basic nature.
