From June 3 & 10, 2022.

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:

- Statistically, asteroid hunters are thought to have discovered 90% of our potentially dangerous celestial neighbors greater than 1 KM in diameter. Thus my Catalina Sky Survey teammate Greg Leonard was surprised to discover 2018 MD1, an unknown very large asteroid moving through the constellation of Perseus.

- An object is tracked in outer space, seen to explode in our atmosphere, and had a fragment of it discovered on the ground. Its analysis will help humans to prepare for and defend against a much larger object with our number on it.
