Planetarium of Medellín, Planetarium in Comuna 4 - Aranjuez, Medellín, Colombia

The Planetarium of Medellín, named after geophysicist Jesús Emilio Ramírez González, stands in the Zona Norte, north of the city center, beside the Parque de los Deseos designed by Felipe Uribe de Bedout. Its first floor, open to all visitors, holds a 200-seat auditorium, a science library, a souvenir shop and a café. A renovation begun in 2011 by Parque Explora added a scientific visualization center.

The planetarium opened on October 10, 1984, conceived by the Astronomical Society of the College of San José under Brother Daniel Julián González Patiño, whose students had proposed the idea. It is named after Colombian geophysicist Jesús Emilio Ramírez González. Renovated in 2006, it was later transformed by Parque Explora with support from the Mayor of Medellín and Bancolombia, adding a scientific visualization center.

The planetarium is named after Jesús Emilio Ramírez González, a Colombian geophysicist. Its surrounding public space, the Park of Wishes, was designed by Felipe Uribe de Bedout to coordinate with the building. The first floor, open to all visitors, holds a 200-seat auditorium, a science library and a café.

Shows take place during the day, so a morning or early afternoon visit gives you the best chance of catching the full program. The building is accessible to visitors with mobility needs and has clear signage throughout.

Although it is an indoor building, the planetarium has observation instruments designed for outdoor use and occasionally sets them up for special open-air events. This makes it one of the few urban science venues in South America that offers sky observations both inside and outside.
