Abstract

The human asteroid body by scanning electron microscopy is surrounded by a tightly adhering network of collagen fibrils. Smaller "satellite" asteroid bodies appear on and partially submerged in the surface of the larger body. Transmission electron microscopy reveals electron-opaque particles symmetrically arranged in these satellite asteroids. X-ray spectroscopy demonstrates the presence of calcium, sulfur, and phosphorus.
