Arrive 45 minutes before sunset for the best experience. The equinox dates (March 20 and September 22) offer the most dramatic alignment with the river horizon.

General admission to the planetarium is around 300-500 ARS (roughly $1-2 USD). The sunset viewing on the grounds is completely free, so you can enjoy the horizon show without buying a ticket.

About
Quick facts: Twice a year during the equinoxes, the sunset aligns perfectly with the city's grid so that the sun drops directly into the Rio de la Plata horizon as seen from this planetarium. The Planetario Galileo Galilei was the first major public building in Latin America built with a fully computerized projection system for its dome.
Highlights: On March 20 and September 22, the planetarium transforms into a celestial observation deck as hundreds gather to watch the sun sink into the horizontal line of the Rio de la Plata, a phenomenon made possible by Buenos Aires' precise east-west street grid. The planetarium's architects designed the reflecting pool in front specifically to mirror the sunset colors, creating a double horizon effect that doubles the visual drama.
