Celestial Globe

 

a globe depicting the celestial sphere with a network of equatorial coordinates and with the ecliptic and the brightest stars. It is usually fitted within two mutually perpendicular rings that are marked off in degrees, which depict the horizon and meridian of a given location. The globe’s axis of rotation can be fixed at any angle to the plane of the horizontal ring. Thus the globe can be placed in such a way as to depict the position of the celestial sphere for a given location at any moment. The celestial globe is used in solving problems of spherical astronomy related to the diurnal and annual motions of the earth.
