The 365 Days of Astronomy Travelers in the Night Eps. 333E & 334E: Worth Tracking & Backwards
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org
From April 2025.
Today's 2 topics:
- Greg Leonard was observing with our team's 60 inch telescope on Mt. Lemmon in Arizona when he discovered a relatively large space rock, 2017 FD157, which can theoretically come closer to the Earth's surface than the communications satellites!
- Dr. Paul Wiegert of Western University in Canada, led a team of astronomers who have determined that 2015 BZ509, a 2 mile diameter object, bucks the solar system traffic by traveling in a direction backwards to all of the planets!
