Product FeaturesA celestial globe model is an auxiliary instrument used for navigation, astronomical teaching, and popularizing astronomical knowledge. People use it to express various coordinates on the celestial sphere, the apparent motion of celestial bodies, and to solve some practical astronomical problems. The sphere is painted with the positions of bright stars, star names, constellations, and the signs and degrees of several celestial coordinate systems. The celestial globe model shows the star patterns opposite to what we see in the sky, which is due to our perspective from outside the celestial sphere, but this has no impact on understanding celestial phenomena. On the celestial globe model, there is a metal axis passing through the center of the sphere, representing the celestial axis, with the poles at the two ends of the axis being the North Pole and South Pole of the celestial sphere. The celestial globe can rotate around the celestial axis. The celestial axis is mounted on a metal ring, which represents the meridian circle (see the celestial coordinate system), and the horizontal ring in the stand represents the horizon circle. The user can adjust the celestial pole height on the meridian circle according to the geographical latitude, and can make the celestial sphere rotate around the pole axis to see the star patterns at different geographical latitudes, on different dates, and at different times. It can also show the moment and direction of the sun's appearance and disappearance, the path across the sky, the moment of the middle of the day, the height, and the length of day and night. The celestial globe is very practical.
