What is the constellation Mars?

In Roman times, Mars-"Mars" was the god of war. The symbol of Mars is a circle with an arrow. The circle represents eternity, and the arrow represents powerful energy. Mars dominates the human head, face and general muscle tissue in astrology, so the fire sign is the most impulsive, willful and even eccentric of the four constellations. Fire signs include Aries, Leo and Sagittarius. Fire signs are characterized by positive, enthusiastic, bright and expansive power, but enthusiasm comes and goes quickly, lacking stability and persistence. They are very creative and like new things. Mars constellation is a dominant planetary constellation. If this ability can be guided or used in a planned or constructive way, Mars will still be busy or full of vitality. For the matter itself, it just needs a driving force, and this force is also a test. The key to success lies in whether Mars has a strong driving force.
