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

Recorded June  13, 2019.

Today's 2 topics:

- In 2018 Asteroid Hunters discovered 1,839 previously unknown space rocks as they passed through our celestial neighborhood. 

- Statistically, asteroid hunters are thought to have discovered 90 to 95% of the Earth approaching asteroids larger than about 3,000 feet in diameter. This group of celestial visitors is important since the impact of one of these giant space rocks  could throw up enough dust and debris to disrupt human food production for a number of years.
