South America brought real energy and creativity to Asteroid Day’s tenth anniversary. Across the region, enthusiastic crowds took part in imaginative, hands-on activities to inform, inspire and celebrate. Here’s a look at the highlights, and perhaps a bit of inspiration for your next event.
In Argentina, the main celebrations took place at Campo del Cielo, the site of some of the world’s largest meteorites. Caravans of students and families joined a vibrant programme of games, exhibitions, workshops and artistic performances.

Meanwhile, Funes Observatory held three weekly workshops in June, giving the public a chance to learn about the features and behaviours of asteroids and comets.

Workshops organised by Funes Observatory focused on asteroids and comets.
In Bolivia, visitors braved the cold in Tarija, nearly 2,000 metres above sea level, to join activities at the National Astronomical Observatory. Its planetarium hosted asteroid projections and an engaging explanation of the importance of Asteroid Day.

The cold didn’t stop people in Tarija, Bolivia, from learning about asteroids.
In Chile, Pueblito de Las Vizcachas once again became the hub of a major celebration. Observatories, science organisations, equipment makers, artists, and outreach teams joined forces to deliver memorable activities about asteroids and planetary defence.

Elsewhere in Chile, exhibitions popped up in several locations. In Atacama, the Andromeda Observatory led an expedition into the desert to teach participants how to identify meteorites on the ground.
In La Serena, the Meteorite Hunting Museum, created specifically to house space rocks, hosted a lecture on asteroid impacts throughout Earth’s history. In and around Santiago, museums such as Mirador showcased meteorite collections, while an inclusive activity organised by AstroUDP and Bibliociegos helped visually impaired participants understand how an asteroid impact led to the extinction of the dinosaurs:

In Uruguay, the Los Molinos Observatory in Montevideo tapped into artistic expression, organising a drawing contest for children aged 3 to 12.

In Colombia, creativity took centre stage, with asteroid science taught in a playful and engaging way. Asteroids inspired a series of hands-on workshops where children and young people created all sorts of imaginative objects, from pop-up books about space rocks to origami shooting stars:

In Brazil, more than 40 cities held Asteroid Day events. In Bauru, a major event organised by the Unesp Observatory included accurate Styrofoam asteroid models, helping participants better understand their shapes:

Most events in Brazil took place in universities, schools, and museums, giving people of all ages the chance to meet astronomers, teachers, and space experts.

Many organisers used Missions to Asteroids Exhibition Posters, helping visitors learn more about asteroid exploration.

3D Asteroid models were popular as well, allowing people to physically compare asteroids with planets and stars.

Online activities were also part of the programme. The Nicolinha & Kids Astronomy Club encouraged children nationwide to post asteroid-related content on social media as part of a friendly contest
