Travelers in the Night Eps. 725 & 726: Mtn Ops & Close Space Rocks

The 365 Days of Astronomy

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 team, the Catalina Sky Survey, would not find a single asteroid without Steward Observatory's Mount Lemmon Operations, or Mtn Ops for short. Bottom line is that Mtn Ops does whatever it takes to make our Asteroid Hunting facilities continue to function.

- Since 1900 there have been 11 close approaches by asteroids larger than 300 feet in diameter. One of them, the Tunguska Object was about 400 feet in diameter. It entered the Earth's atmosphere and exploded with such force that it blew down trees over an 800 square mile area in 1908. Hopefully that will not happen again anytime soon.
