  • Where Is the Asteroid Belt Located in Our Solar System?
    One AU is the average distance from Earth to the Sun, roughly 150 million kilometers This places the asteroid belt separated from the terrestrial planets The belt forms a broad, somewhat flattened ring around the Sun, rather than a thin, dense band Its total width is about 1 AU
