Podcaster: Dr. Al Grauer
Title: Travelers in the Night Eps. 761 & 762: Allesandra’s Duo & Kacper’s PHA
Organization: Travelers in The Night

Description: Today’s two stroy:
- In less than two hours my Catalina Sky Survey teammate Allesandra Serrano discovered two small fast moving space rocks. Both of them passed through the Earth-Moon system unimpeded. Other space rocks are not so lucky.
- An object like 2023 MN5 impacts Earth once every 90,000 years or so creating a crater 5 miles in diameter an 1800 feet deep in sedimentary rock. 50 miles from the impact of such an object observers would feel the effects of a 7.1 Richter scale Earth. Rest assured that asteroid hunters will continue to track 2023 MN5 as it passes near Earth and Jupiter to make sure that its orbit does not change to make it a threat to humanity.
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.
