Aries is the first sign of the zodiac and is associated with the element of fire and is ruled by the planet Mars. People born under this sign are often described as confident, energetic, and competitive, but they can also be impulsive, impatient, and sometimes aggressive. In astrology, the position of the sun, moon, and other celestial bodies at the time of a person's birth can influence their personality traits, strengths, weaknesses, and tendencies.
