A planetarium is an indoor theatre built that presents high tech multimedia shows about astronomy, night sky, the solar system and beyond. We can see the stars, planets and other celestial objects moving realistically the same as the real world. The example of title film in planetarium are the solar system, the earth, the galaxy and etc.
The chair in planetarium is unic because it can change degree from 450 to 1800 by ourself, but can not rotate 3600 from right to left or left to right. The size of bulit planetarium is more 3 meter and accomodate more 1 person.
2.2 History of Planetarium
The first idea of planetarium is visual aids to show how the things in space move. Example : star, planet, sun, earth, and comet. In 19 century, planetarium that visual aids is called orrey. The first projectors of planetarium created by Walther Bauersfeld in 1919. In August 1923, the first projector that called Model I setted in Carl Zeiss Company, Jena. Bauersfeld for the first time organized show in front of people with that projector in Deutsches Museum Munchen, October 23, 1923. So thar, Deutsches is the first planetarium in the world after the projector setted permanently in Mei, 1925. At beginning world war II, projector is taken apart and hidden from public. After Deutsches Museum broken because world war II, Deutsches Museum rebuilt again and Model I projector is setted again in Mei 7, 1951.
2.3 Technology of Planetarium
Planetarium is divided by two technology. Those are domes and projectors. Domes is screen like a half of ball and its special ceiling of planetarium. This ceiling is made of panel alumunium. This ceiling cannot open. Its different with observatory. The ceiling of observatory can open every time when they want to look the sky. The diameter of planetarium domes ranges in size from 3 to 30 m. The built accomodate from 1 to 500 people in there.

Picture 3. Projector
The projector give the picture from more one lens. The shape of projector is like ball. In body of projector have many the lens. The size of lens is not same. From this lens, the information sent to domes and domes bounce back to our eyes. In planetarium has moderator to give
information about the film that we see. The moderator speak and explain about all that film..
The projectors of planetarium is two kind. Those are optical projector and digital projector. The digital projection system accurately displays stars, planets and other celestial bodies on its dome screen, allowing you to journey through space without ever leaving your seat. In planetarium, we feel truely space station in the dark.

In modern, planetarium can enjoy in our homes by computer. That is about software of planetarium. Software of planetarium is change from three dimension to two dimension. In internet we can get many software freely. One of that software is stellarium.
