Author: Albert D. Grauer April 15, 2025 Duration: 2:01
Asteroid hunters have become aware of the many small space rocks which come near Earth because of improvements made to telescopes, cameras, and computer analysis software. Recently, my Catalina Sky Survey teammate Rose Matheny used her skills and a new camera to discover the second small space rock in 32 days which came between the communications satellites and the Earth's surface. Rose spotted her 10 to 12 foot diameter space rock as it approached the Earth more than a million miles away with its little full moon face pointing towards us. 31 hours later, her discovery, 2017 GM, came to within 10,100 miles of Earth as it streaked by at about 11 mi/s on its way towards an encounter with Venus five and a half weeks later. It it had been on an impact trajectory with our planet, Rose's early detection would have allowed asteroid hunters to alert humans to prepare for a spectacular light show as it exploded in our atmosphere.

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.
