Construction began under the direction of architect Enrique Jan in 1962, and it was inaugurated on December 20, 1966.
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.
The museum has a piece of lunar rock which was brought back to Earth by the Apollo XI mission and gifted to the planetarium by Richard Nixon.
