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 July 2025.
Today's 2 topics:
- Recently, my Grandsons, Dane and Hank joined our asteroid hunting team at the Catalina Sky Survey 60 inch telescope on Mt. Lemmon. The most interesting of our discoveries, 2017 KJ32 is only 16 feet in diameter, orbits the Sun once every 315 days, and can come closer to us than the communications satellites.
- My Catalina Sky Survey teammate Carson Fuls discovered a 33 foot diameter asteroid which has about a 1.1% chance of impacting the Earth on 569 encounters with our planet between 2045 and 2116. Its name is 2017 LD. It is on the list of the most likely objects to strike the Earth in the next hundred years as reported on NASA's Sentry Earth Impact Monitoring table.
