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 2024. Today's 2 topics: - When asteroid hunters follow an object in the night sky for a few hours or a couple of days they are only able to observe a snippet or tracklet of the object's hundreds to thousands of days long path around the Sun. If we only have a short sample of an orbit we loose precision to locate the object as the length of time since the last observation increases. It is thus possible to lose the knowledge of where to find a particular asteroid. - It's a good thing this one will miss Earth! Riding the surface of the asteroid that my Catalina Sky Survey teammate Richard Kowalski recently discovered would be an incredible experience.
