Comets are not stable over the age of the Solar System (few billion years)… and neither are meteor showers, trails of dust left by comets. Pilorz et al. ponder that instability- nothing much on human timescales, I’ll say.
And speaking of showers, the Chinese have built new radars, useful for flying objects and the plasma tails they generate. This includes radars in southern China, much like Arecibo was placed in Puerto Rico. Lu et al. report on their meteor detections, including claims of a new shower.
…and speaking of collective bodies and population statistics, Pichierri et al. consider the Kuiper Belt as an aggregate. Are there patterns? Remember, Hirayama and Kirkwood found patterns in the Main Belt all the way back when there were few Belt objects known- the statistics were already shaping up with just hundreds of asteroids.
