John Batchelor and I welcomed Dr. Paul Chodas to the program to discuss the recent discovery and identification of the interstellar object identified as A/I2017 U1. This object was later given the Hawaiian name 'Oumuamua. Our guest talked about it likely coming from the Constellation Lyra and Vega. We talked about its very high speed which seemed to be about 25.5 kilometers per second (15.8 mps). Dr. Chodas said the object was about 200-300 meters in size and reddish in the spectrum. Later in the segment, we talked about how Dr. Chodas calculated the orbit and the work he has done in this area since 1990. We asked how this work has changed over the decades. In addition, don't miss the part where we learned that astronomers had been expecting such objects for decades but this was the first time one was actually found. It was a very interesting story.
