Product Details
Planetarium
Celestial sphere model is an auxiliary instrument used for teaching navigational astronomy and popularizing astronomical knowledge. People use it to express the various coordinates of the celestial sphere, the apparent motion of celestial bodies and to solve some practical astronomical problems. The positions of bright stars, star names, constellations, and the signs and degrees of several celestial coordinate systems are painted on the sphere. The celestial phenomena on the celestial sphere are exactly opposite to those seen from the sky. This is because the celestial sphere is viewed from outside the celestial sphere, but this has no effect on understanding celestial phenomena. There is a metal axis on the celestial sphere that runs through the center of the sphere, representing the celestial axis. The two ends of the axis are the north and south poles of the celestial sphere. The celestial sphere can rotate around the celestial axis. The celestial axis is mounted on a metal circle. The metal circle supporting the axis represents the meridian circle (see Celestial Sphere Coordinate System. The celestial sphere is placed on a mount. The horizontal ring in the frame represents the horizon circle. The user can adjust the celestial sphere on the meridian circle according to the geographical latitude. Adjust the height of the celestial pole and make the celestial sphere rotate around the polar axis to see the starry sky scene at different geographical latitudes at different dates and times, as well as the horizon longitude (azimuth angle) and horizon latitude (horizontal height) of a certain celestial body. It can also be displayed The time and azimuth of the sun rising and setting on a certain day, the height of the mid-heaven moment in the celestial path, and the length of day and night. The celestial sphere is of great practical value.
