Title: Travelers in the Night Eps. 685 & 686: Exiled Asteroid & Big Atira

Organization: Travelers in The Night

Link : Travelers in the Night ; @Nmcanopus

Description: Today’s two stroy:

  • An asteroid is exiled to the outer regions of the solar system during Jupiter’s rampaging tack away from the Sun long ago. During that process enough material was left in Jupiter’s wake to form Venus, Earth, Mars, and the asteroid belt as we know them today.
  •  The recent discovery of an asteroid, whose orbit lies completely within that of the Earth, reminds asteroid hunters to continue to search near the Sun so that a large dangerous object does not sneak up undetected on the residents of planet 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.
