Podcaster: Dr. Al Grauer
Title: Travelers in the Night Eps. 695 & 696: A Large Visitor & Botswana Fragment
Organization: Travelers in The Night
Description: Today’s two stroy:
- 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.
Bio: Dr. Al Grauer is currently an observing member of the Catalina Sky Survey Team at the University of Arizona. This group has discovered nearly half of the Earth approaching objects known to exist. He received a PhD in Physics in 1971 and has been an observational Astronomer for 43 years. He retired as a University Professor after 39 years of interacting with students. He has conducted research projects using telescopes in Arizona, Chile, Australia, Hawaii, Louisiana, and Georgia with funding from NSF and NASA.
He is noted as Co-discoverer of comet P/2010 TO20 Linear-Grauer, Discoverer of comet C/2009 U5 Grauer and has asteroid 18871 Grauer named for him.
