The spacetime structure and properties of the solution of dust particle are discussed. We derive the discrete structure of interior space of dust particle, and prove that the matter ball in the interior of dust particle is a flat ball without coordinates and has minimal volume and unitariness. Then, we derive the radial geodesics in the interior and exterior spacetime of dust particle and prove its continuity. Finally, we expound the inherent links between matter, gravitation and spacetime which were brought to light in the solution of dust particle.
