Travelers in the Night Eps. 693 & 694: Comet Leonard III & Comet Catalina

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 Today's 2 topics: - My Catalina Sky Survey teammate Greg Leonard knew he had bagged his third comet when he spotted an unknown fuzzy object with a broad tail moving through the constellation of Pisces. Eventually when P/2018 L5 (Leonard) looses its volatile materials Comet Leonard will become one of the countless millions of main belt asteroids circling our Sun. - Comet C/2018 M1 (Catalina) is eternal in the sense that it will likely wander the vast space between the stars in our Milky Way Galaxy until the end of time.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
