Little Plutino Has An Atmosphere and Making Sense of Saturn

A Plutino, an object that shares Pluto's orbit but which is much smaller than Pluto, appears to have a very thin global atmosphere. We discuss the detection and how such a small body could hold onto even a thin atmosphere, as well as a new model that describes many of Saturn's peculiarities with a recent collision between its big moon Titan and a precursor to the sponge-y moon Hyperion. Join us for all this, space news, astronomy trivia, and much more.
