The planetarium was thought since the original project and for this end the sphere was built, it was early used to show some exhibitions before its habilitation. The structure, from the beginning, is an integration of two structural systems: the low part (from the equator) is made of reinforced concrete and the upper part is formed with concentric ribbings made of steel and cells of a light material with a cover of concrete in both sides, in its external face its covered with green ceramic tiles. The principal requirement was to design a projection room for 280 persons, having as norm of operation the technology of “ Theaters of Immersion” which consists in projecting with 6 heads located in the perimeter of the auditorium to a dome which geometry describes a spheres segment of 165° from the equator, that at the same time has a 20° inclination. This dome is built with aluminum with a higher level of purity than the commercial one and has a structure of rectangular tubes that form a frame from which chains hang and suspend the dome from the structure. That´s why it is considered a delicate and fine piece. Between the wall and the dome base, there is a space from where the lights of the projectors come out. The grades are traced in function of the radius of the projection dome. In each row, sits are placed with different inclinations, according to the angle required in the endorsement and to the height of each row and its position in respect to the projection dome. This generates different width in the rows which need more space when they have a higher reclination.
