Travelers in the Night Eps. 865 & 866: New Potentially Hazardous Asteroid & Interstellar Visitor
Sunday, 22 March, 2026
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From September 2025. Today's 2 topics: - On a short June night my Catalina Sky Survey teammate Greg Leonard was observing with our 60 inch telescope on Mt. Lemmon, Arizona in the constellation of Ursa Major when a relatively bright fast moving point of light appeared in a set of his images. Even though on its current path Greg's discovery, 2025 MM89, has virtually no chance of impacting our home planet asteroid hunters will continue to track it to make sure it doesn't become a threat as it passes other objects in space. - Amazingly, nature occasionally sends an interstellar traveler through our solar system for us to observe. The third such object that astronomers have discovered coming into our solar system from truly deep space is 3I/ATLAS. It was discovered as it streaked towards the inner solar system at 130,000 miles per hour by the ATLAS team's 20 inch telescope in Chile and was quickly tracked by telescope around the world.
