Yea, I know. From the same or similar idiots that tell us we “climate change”. These so called scientists are the biggest joke ever hoisted on mankind.
The designation of planet is rather arbitrary and non-scientific in the first place, being based upon its original definition of being as “wanderer” in the sky. So too were all manner of asteroids. Ceres too is a planetoid in a Solar orbit, but we did not classify it as a major planet.
