The asteroid belt that lies between Mars and Jupiter is known as the "Main Asteroid Belt." This region is populated with numerous rocky bodies, ranging in size from tiny pebbles to the dwarf planet Ceres. It is believed to be remnants from the early solar system that never coalesced into a planet due to the gravitational influence of Jupiter. The asteroid belt serves as a significant area of scientific study, helping researchers understand planetary formation and the composition of celestial bodies. Exploration missions, such as NASA's Dawn spacecraft, have provided valuable insights into the characteristics of asteroids within this belt.
