843-Possible Impactor

843-Possible Impactor

Author: Albert D. Grauer April 4, 2025 Duration: 2:01
On 27 December 2024 the Atlas group in Chile discovered an object now known as 2024 YR4 which appeared to have a significant chance of impacting Earth 22 December of 2032. The most recent data indicates the chance that 2024 YR4 impact Earth is about 1 in 25,000.  These data indicate our moon has about a 1 in 700 chance to be impacted by this space rock. Even so astronomers are preparing for 2028 when 2024 YR4 willagain come within the range of our instruments.   Current data indicates 2024 YR4 will miss the Moon by less than 1000 miles on  2032 December 22 giving astronauts there a Merry Christmas.

Each episode of Travelers In The Night feels like a quiet, personal conversation under a dark sky. Hosted by astronomer Dr. Albert D. Grauer, this podcast brings the distant cosmos into sharp, intimate focus. Dr. Grauer isn't just an observer; he's an active participant in the hunt, working with the Catalina Sky Survey team that has consistently discovered near-Earth asteroids for years. In these brief and engaging segments, you'll hear firsthand accounts of what it's like to track these ancient celestial travelers-the asteroids and comets that silently pass by our world. The discussions move beyond simple facts to explore the real-world implications of these discoveries, from planetary defense to the sheer wonder of our dynamic solar system. Accompanied by the contemplative music of John Lyell's "Eternity," each installment offers a moment of calm reflection on humanity's place in the universe. It’s a perfect blend of grounded science and cosmic curiosity, making complex astronomical concepts accessible and deeply fascinating. For anyone who has ever looked up and wondered what's out there moving in the dark, this podcast provides a direct line to the front lines of discovery.
