The "rising sign," also known as the ascendant, is the zodiac sign that was on the eastern horizon at the exact moment of a person's birth. It plays a crucial role in astrology, influencing how individuals present themselves to the world and how others perceive them. The rising sign can affect personality traits, appearance, and overall demeanor. In a natal chart, the rising sign is determined by the time and location of birth. It is one of the three key components of a person's astrological profile, along with the sun sign and moon sign. Understanding the rising sign can provide deeper insights into one's character and life path.
