We study the static spherically symmetric Einstein-Yang-Mills equations with SU(2) gauge group and find numerical solutions which are nonsingular and asymptotically flat. These solutions have a high-density interior region with sharp boundary, a near-field region where the metric is approximately Reissner-Nørdstrom with Dirac monopole curvature source, and a far-field region where the metric is approximately Schwarzschild.
