Travelers in the Night - Eps. 247 & 248: Potential Mining Target & Incoming

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. Today's 2 topics: - The Catalina Sky Survey team members Greg Leonard & Richard Kowalski discovered 2016 GC221, a prime target for asteroid mining, though it is traveling a bit faster than we'd prefer. - Catalina Sky Survey team member Greg Leonard discovered 2016 CG18 which was used recently as a test object for rapid response observing protocols. 2008 TC3, by the way, WAS on such a collision course with Earth, but exploded harmlessly over the Nubian desert on October 7th, 2008.
