This is the largest planetarium in Switzerland and is essentially an 18m-diameter dome cinema with a projection area of 508m2. A variety of films are shown each day, some of which are well suited for a younger audience. All projections are in German, but simultaneous translations in English via headphones are offered in many cases. Opened in 1969, the same year Neil Armstrong set foot the moon, the Planetarium is currently showing a film called Back to the Moon about the current space race and the innovative approaches in engineering employed to achieve it. The film ends with a projection of a possible scenario for a future on the moon. Tickets for the Planetarum are sold separately from the Transport Museum, but it's possible to buy a combined ticket for both. A great option for a rainy day.
