Title: Travelers in the Night Eps. 739 & 740: Comet Groeller & Asteroid Billiards
Organization: Travelers in The Night

Description: Today’s two stroy:
- My Catalina Sky Survey teammate Hannes Groeller was asteroid hunting with our Schmidt telescope on Mt. Bigelow, Arizona when he discovered his first comet: P/2019 B2 (Groeller). After the Sun bakes out all of the frozen gasses, Hannes’s Comet, will lose its coma and tail and become indistinguishable from one of the millions of main belt asteroids orbiting the Sun between Mars and Jupiter.
- NASA’s Double Asteroid Redirection Test or DART for short will test methods to make a dangerous asteroid miss Earth.
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.
