Description

- Product Information
- Name: 32cm 3D Globe
- Brand: Sky Dove
- Product Code: 320AY-18
- Product Features
- The celestial globe model is an auxiliary instrument used for navigation, astronomical teaching, and popularizing astronomical knowledge. People use it to express various coordinates of the celestial sphere, the apparent motion of celestial bodies, and to solve some practical astronomical problems. The surface of the globe is marked with the positions of bright stars, star names, constellations, and the signs and degrees of several celestial coordinate systems. The star patterns on the celestial globe are exactly the opposite of what we see in the sky, which is due to the fact that we observe the celestial globe from the outside.However, this has no impact on understanding celestial phenomena. There is a metal axis through the center of the celestial globe, representing the celestial axis, with the poles at the two ends 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 celestial coordinate system), and the horizontal ring in the stand represents the horizon circle. Users can adjust the celestial pole height on the meridian circle according to the geographical latitude, and can make the celestial sphere rotate around the polar axis, thus seeing the starry sky scenes at different geographical latitudes, different dates, and 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.
