Title: Travelers in the Night Eps. 723 & 724: Very Close One & Aten
Organization: Travelers in The Night
Link : Travelers in the Night ; @Nmcanopus
Description: Today’s two stroy:
- Ten hours and 46 minutes after my Catalina Sky Survey teammate Greg Leonard discovered a Toyota RAV4 sized space rock, now named 2018 UA, streaking through the constellation of Pegasus at 8.8 miles/second, this tiny asteroid passed less than 1/2 the distance of the communications satellites to the surface of planet Earth.
- Aten Asteroids are stealthy space rocks which can be dim and hard to detect since for most of their path about the Sun their illuminated side is facing away from us.
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.
