The Moscow Planetarium was opened in 1929 and became the first in the Soviet Union and the thirteenth in the world. After the closure in 1994 and global reconstruction, it was reopened in summer of 2011. The Planetarium has the largest dome-screen in Europe of 25 meters in diameter for exhibition of astronomical films.
In addition, the Moscow Planetarium houses a Urania Museum with mock-up models of space vehicles, a collection of meteorites and relief globes of planets. In the interactive "Lunarium" visitors can drive the Mars rover vehicle, as well as try out the operating astronomical devices in the Sky Park.
