Abstract
An artificial satellite and artificial satellite system has power transmission and reception efficiency and includes an expandable solar panel that generates power, expandable power transmitting antennas, and expandable beam members to connect the solar panel and the power transmitting antennas to each other. The beam members are expanded from being provided in the artificial satellite, on a plurality of rotational symmetry axes of an imaginary polyhedron formed with substantially a center of the artificial satellite as an origin. The beam members are arranged at substantially equal distances in directions of the rotational symmetry axes. A light receiving surface of the solar panel and installation surfaces of the power transmitting antennas, when expanded, are substantially perpendicular to a solar panel rotational symmetry axis passing through a center of the solar panel, and being arranged on opposite sides of a plane passing through the center of the artificial satellite.
