Ep. 745: How We Know If Asteroids Will Attack

Astronomy Cast Ep. 745: How We Know If Asteroids Will Attack By Fraser Cain & Dr. Pamela Gay Streamed live Feb 20, 2025. I'm sure you've heard the news, asteroid 2024 YR4 has a tiny chance of hitting Earth in 2032. How do astronomers discover these dangerous asteroids, measure their future impact risk and track the changes over time? When should we panic? New asteroids are found every day, and every day we learn that those asteroids don't have any murderous intentions. But how do we learn that? In this episode we dig into asteroid orbital determination. Hosted by: Fraser Cain and Dr. Pamela L. Gay SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.
