- Abstract : CELLINOID shape model defined by six semi-axes is similar to Ellipsoid with three semi-axes. Due to its asymmetry, this shape model could be adopted to simulate the bodies with asymmetric shape in astronomy, such as the asteroid. In this article we explicitly analyze the center of mass and the moment of inertia of CELLINOID. Furthermore, how to determine the principal rotatinal axis corresponding the largest moment of inertia is discussed also. The analyzed results of CELLINOID will be cited directly in the corresponding research. Paragraph headings: 1. Introduction 2. Center of mass 2.1. Center of mass of one Octant 2.1.1.
