Professor Aristóteles Orsini Planetarium

Professor Aristóteles Orsini Planetarium is a circular building located within Ibirapuera Park that houses a domed projection space. The interior features reclining seating arranged in tiers, allowing visitors to watch astronomical shows and celestial displays projected overhead.

The facility was established in 1957 as Brazil's first planetarium. An advanced projection system imported from Germany allowed audiences to view detailed representations of the night sky for the first time.

The space functions as a meeting point where visitors from all backgrounds come to explore the cosmos together. Inside, the shared experience of watching the sky unfold overhead creates a sense of connection among strangers seated side by side.

The planetarium welcomes visitors on weekends, while weekdays are typically reserved for school group visits. Plan ahead by checking available session times, as the limited number of daily showings fills up quickly.

The projection setup uses multiple specialized devices working together to create realistic displays of stars, planets, and cosmic events across the dome. This technical approach allows complex astronomical phenomena to be shown in a way that feels immediate and comprehensible.
