Planetarium Wolfsburg gives the city a good indoor science stop, especially useful for families or for travellers who have already done the Autostadt and art museum circuit. The dome shows cover astronomy and related visual programmes, turning a compact visit into something more immersive than a standard exhibit hall.
Because the experience depends on the schedule, check language and show times before going. It is close enough to central Wolfsburg to fit around other sights, and it broadens a city that visitors often reduce too quickly to Volkswagen.
