380E-416-Odd Ball

Author: Albert D. Grauer March 17, 2026 Duration: 2:01
The orbits of the planets are closely aligned with the extension of the Sun's equator into space and are contained within the flattened disk of material which forms the plane solar system. Most asteroids have orbits with inclinations or tilts to the solar system's plane which are less than 20 degrees. Thus, when my Catalina Sky Survey teammate Rose Matheny discovered a small space rock which soars into the lonely space high above and below our solar system's plane, it got our attention. As with all of our asteroid discoveries, Rose had no idea of what kind of object she had discovered with our Schmidt Telescope on Mt. Bigelow, Arizona until it had been tracked by observers around the world. The Minor Planet Center used the data from 14 different telescopes to calculate an orbit, estimate a size, and give the new object the name, 2017 TF4. Rose's odd ball near Earth Apollo asteroid discovery , 2017 TF4, has an orbit which is tilted by 60 degrees to the plane of our solar system. It's inclination or tilt is greater than 99.5% of the other 8,000 known Earth approaching Apollo asteroids. 2017 TF4, Rose's 260 foot diameter discovery orbits the Sun at about the same distance as the Earth once every 414 days. Perhaps as asteroid hunters discover additional small objects with orbits similar to Rose's discovery we will be able to trace them back to when they were created by a catastrophic collision long ago.

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.
