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

<p>Dr. Al Grauer hosts. Dr. Albert D. Grauer ( <a href= "https://twitter.com/Nmcanopus">@Nmcanopus</a> ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. <a href= "http://travelersinthenight.org">travelersinthenight.org</a></p> <p><strong>Today's 2 topics:</strong></p> <p>- 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.</p> <p>- 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.</p> <p> </p> <p>We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.<span class= "Apple-converted-space"> </span></p> <p>Just visit: <a href= "https://www.patreon.com/365DaysOfAstronomy">https://www.patreon.com/365DaysOfAstronomy</a> and donate as much as you can!</p> <p>Share the podcast with your friends and send the Patreon link to them too!<span class="Apple-converted-space"> </span></p> <p>Every bit helps!
