Travelers in the Night Eps. 783 & 784: Kacper's Centaur & Josh's Two PHAs

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:

From February 2024.

- Centaurs have long puzzled astronomers since they have traits in common with both asteroids and comets.

- So far asteroid hunters have discovered approximately half of the 5,000 PHAs which are likely to exist. Asteroid hunters will continue to search the sky to discover dangerous asteroids 50 years before impact so that humans can either deflect or pulverize them.
