Planetario Galileo Galilei
A silver dome in Palermo where you can stand next to a moon rock gifted by Nixon, then watch 8,900 stars wheel across a 20-metre aluminium sky.

Opened in 1966 inside Parque Tres de Febrero, this planetarium pairs southern-sky projections with a genuine Apollo 11 lunar sample and 100-million-year-old ammonite fossils from Neuquén Province. Six 4K Barco projectors replaced an original rig of over 100 projectors weighing 2.5 tons — the gap between those two numbers tells you how far projection technology has traveled.
What to look for
- Apollo 11 moon rock inside the museum — brought back by the mission and donated by Richard Nixon
- Metallic meteorite from Chaco Province on the entrance terrace, visible before you buy a ticket
- The 20-metre reflective aluminium dome interior and the six Barco I600-4K10 projectors that replaced a 2.5-ton array of over 100 projectors
Inside Parque Tres de Febrero, Palermo — the dome runs scheduled sessions, so check show times before arriving.
