1.Planetarium is an apparatus that is used to display the astronomical phenomena.

2.Optical planetarium is used to portray vividly astronomical phenomena on projection domes through optical projection. A true to the nature star-lit firmament is formed to simulate the motion of celestial bodies, including first of all that of the fixed stars. It can also depict motions of the sun, the moon, and the planets as they move along their individual tracks on the sky. Visible sky with the multitude of heavenly bodies as seen by people at different longitudes and latitudes of each heavenly body can be measured. And with the help of a wide series of accessories it is possible to provide the audience with a full range of colorful astronomical phenomena at will.

3.The majority of planetarium projectors take their external shape similar to a dumbbell, with a multitude of star projection lenses on both spheres at its extremity, projecting the visible stars and the Milky Way. Within the cage-shaped structure situated between the spheres ate mounted the drives for the demonstration of the motions of the solar system, namely that of the sun, the moon and the major planets: Mercury, Venus, Mars, Jupiter and Saturn. Their visual motions in their respective loci are simulated through each of their specific mechanisms and transmissions, consisting of precision fearing and drives.
