Planetario Galileo Galilei: reaching for the stars

The thought of our city having a planetario (or planetarium) began in 1958. Councilman José Luis Peña and the municipal Secretary of Culture, Dr. Aldo Cocca agreed to its construction. Work started in 1962 under the direction of architect Enrique Jan. It was inaugurated on December 20th, 1966. The first function was carried out on June 13, 1967, and the facility was officially opened to the public on April 5th, 1968.

The building has five floors, and a 20 metres (66 ft) diameter room with 360 seats. The inside of the 20m semispherical dome is covered with reflective aluminium.

The planetarium itself is located in the centre, it has over 100 projectors and is approximately 5 metres (16 ft) in height and 2.5 tons in weight. It consists of a cylindrical framework with independent projectors for the Moon, the Sun and the visible planets (Mercury, Venus, Mars, Jupiter and Saturn) and two spheres in the extremes that project 8,900 stars, constellations and nebulas.
