NASA PI's Argue Over The Definition Of "Planet" On Twitter - Again

As you know Carolyn, or used to know, science doesn't work that way. And no one owns the word planet anymore than anyone owns knowledge. Science isn't dogma and is always open to challenge as ideas mature. Embrace the debate. . — Alan Stern (@AlanStern) July 4, 2019

Science worked exactly the way it should when new findings revealed conclusively that Pluto had been mis-classified. Dynamical circumstances (member of belt, resonantly or tidally forced, etc) are of paramount importance. 'Round' is laughable. And indeed, ppl are laughing! — Carolyn Porco (@carolynporco) July 4, 2019
