Deflecting Danger in 2032 from Asteroid 2024 YR4 | What Is It? What Can We Do?

On today’s episode, we’re diving into what’s going on with Near-Earth Asteroid 2024 YR4. You may have heard online that this asteroid is on a trajectory to impact Earth on December 22nd, 2032. It’s captured the zeitgeist and everyone’s talking about it. 

But what can we do in the meantime? We say - Let’s learn! We need to science the $%#t out of this one! We’re going to explore the idea of planetary defense, the level of impact if it does hit Earth in 2032, and how lucky we are to have successful missions like DART and HERA to lean on for our “armageddon” moment. 

We'll also try to answer these questions:

• What is the Asteroid?
• What is the impact potential on Earth?
• How was it discovered?
• Why do the impact probabilities keep changing?
• What can we do about it?
• Why don't we just NUKE it?

Here's to building a fantastic future - and continued progress in Space (and humanity)!  Spread Love, Spread Science
