International Asteroid Day: A Reminder That Asteroids Fly, and We Should Pay Attention

June 30th marks International Asteroid Day, a day dedicated to raising awareness about the potential threat posed by near-Earth objects (NEOs). It’s not just a sci-fi movie plot – asteroids are real, they fly through space, and some have the potential to collide with our planet.

But before we start panicking, let’s look at the facts:

• There are millions of asteroids in our solar system. The vast majority pose no threat to Earth.

• NASA currently tracks over 28,000 near-Earth asteroids. These are asteroids that come within 30 million miles of our planet.

• The vast majority of these NEOs are small. They’re likely to burn up in our atmosphere before they can cause significant damage.

• However, there are some large asteroids out there. The largest known NEO, 1036 Ganymed, is about 16 miles wide.

The Importance of Asteroid Awareness

While the odds of a catastrophic asteroid impact are low, the potential consequences are high. The Chicxulub impact, which wiped out the dinosaurs 66 million years ago, was caused by an asteroid roughly 6 miles wide.

International Asteroid Day is a chance to:

• Learn more about asteroids and the threat they pose.

• Support research and development of asteroid detection and deflection technology.

• Encourage global cooperation to mitigate the risk of asteroid impacts.

A Real-World Example: The Chelyabinsk Meteor

On February 15, 2013, a meteor exploded over Chelyabinsk, Russia. While it was relatively small, estimated at about 60 feet wide, it still caused significant damage. The shockwave shattered windows and injured over 1,500 people.

This event serves as a stark reminder that even relatively small asteroids can have a devastating impact. It highlights the importance of continued research and development to improve our ability to detect and potentially deflect potentially hazardous asteroids.

What Can You Do?

There are many ways to get involved in International Asteroid Day:

• Learn more about asteroids. Visit NASA’s website or the International Asteroid Day website for more information.

• Share your knowledge with others. Talk to your friends and family about the importance of asteroid awareness.

• Support organizations that are working to protect Earth from asteroids. Donate to organizations like the B612 Foundation or the Planetary Society.

International Asteroid Day is not about spreading fear, but about promoting awareness and action. By understanding the potential threat posed by asteroids, we can take steps to mitigate the risk and ensure a safer future for our planet.
