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: - So far asteroid hunters have discovered about 8,000 of the 25,000, large, potentially hazardous asteroids, suspected to exist, leaving 17,000 more to be found. For this reason, NASA has designed and proposed the NEOCam spacecraft to give us the ability to find them before they find us. - In the early evening of January 17, 2018 six hundred and seventy four observers in 11 States and Canada reported a fireball meteor streaking across the sky to the American Meteor Society. To find freshly fallen meteorites visit the American Meteor Society's website but do not hunt for meteorites on private land without permission.   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!
