PURPOSE: A celestial globe for education is provided to improve a leaning effect of a learner and to reduce financial burdens by using thick paper. CONSTITUTION: A celestial sphere is comprised of an equator ring(4c), meridian rings(4b, 5a), and a meridian ring connection disk(4a). The equator ring conforms to an equator of the celestial sphere. The meridian rings are vertically connected to the equator ring. The meridian rings conform to a meridian line. The meridian ring connection disk is connected to both ends of the meridian rings. An axial rod passes through the meridian ring connection disk. The axial rod conforms to an axis of rotation of earth on the celestial sphere. A circular sphere(2) of predetermined size is located on the center of the celestial sphere. The axial rod passes through the circular sphere. The circular sphere conforms to the earth on the celestial sphere. A horizontal plane disk(4d) freely moves on the circular sphere. A base frame passes through the bottom of the axial rod and forms a supporting board. The supporting board fixes the celestial sphere to predetermined angle. |
