Asteroid Day celebrated in Luxembourg

It’s time for Asteroid Day! The Asteroid Day 2024 celebration in Luxembourg is on June 28 and 29, 2024. Asteroid experts will converge on Luxembourg to take part in a packed two-day program of speakers and festival booths. The program for Asteroid Day’s 2024 edition will be “education on asteroids and space highlighting the importance and impact of space down to Earth“.

Why Asteroid Day?

Asteroids are leftover remnants of the birth of the planets in our solar system. In addition, they’re full of resources that might someday be used by humanity. However, they are also hazards. With this in mind, astronomers keep a close watch for any asteroids possibly headed toward Earth. said:

Space plays an increasingly important role in the development of our economy and society. For the ninth consecutive year, the Asteroid Day gathers a global community of people who are passionate about space and want to learn about the history of our solar system, the future of space exploration, technologies and businesses, and ways to protect and prosper our planet.

We are particularly eager to attract young and talented people and give companies of the flourishing space cluster in Luxembourg an excellent opportunity to showcase their activities and tell their stories. We thank our sponsors and partners, in particular the Luxembourg Space Agency (LSA), and look forward to making Asteroid Day 2024 another success. Join us on site or online and don’t miss the opportunity to meet world famous scientists and astronauts, learn about Space, and have fun.

The speakers for Asteroid Day 2024 – featuring experts and celebrities, and covering a broad range of asteroid science and research – are the backbone of Asteroid Day 2024.

History of Asteroid Day

Supporters hold Asteroid Day on June 30 each year to mark the date of Earth’s largest asteroid impact in recorded history, the Siberian Tunguska event. Asteroid Day was established in 2014. The co-founders of Asteroid Day were astrophysicist and famed musician Brian May of the rock group Queen, Apollo 9 astronaut Rusty Schweickart, filmmaker Grig Richters and B612 Foundation president Danica Remy. Their goal was to educate the public about the importance of asteroids in our history and the role they play in the solar system.

Then in 2016, with the leadership of the Association of Space Explorers (ASE), the United Nations declared Asteroid Day to be a global day of education to raise awareness and promote knowledge in the general public about asteroids.

So each year Asteroid Day presents the public with a snapshot of cutting-edge asteroid research from the largest telescopes on Earth to some of the most ambitious space missions.

Bottom line: The annual Asteroid Day program will be held in Luxembourg on June 28 and 29, 2024. Also, Asteroid Day is celebrated around the world on June 30. Check here for events near you.
