The Planetarium and Astronomical Museum of Rome is a museum and educational complex based at the Museum of Roman civilization in the EUR district. It is a municipal museum, and is therefore part of the "Shared Museums" system. It was inaugurated on May 26, 2004, more than 20 years after the closure of the historic planetarium housed in the Octagonal Hall of the Baths of Diocletian. The planetarium consists of a 14-meter dome in which, by means of three digital projectors, simulations and all-sky projections of celestial bodies and nebulae are reproduced, in addition to the traditional reproduction of the starry sky, the motions of the Moon and the planets. The complex also offers an extensive program of live astronomical shows, conferences, events and astronomical observations for informational purposes. The adjacent astronomical museum offers large models of the planets, dioramas and interactive multimedia stations with astronomical video games that allow the visitor a real immersion in the spatial context, experiencing science without losing the ability to be surprised and excited. The spaces of the Astronomical Museum will be constantly updated and will open to temporary exhibitions and displays on the main celestial events and the most recent astrophysical discoveries.
