Pluto will always be a planet
Nostalgia for your very educated mother serving pizza is clouding your eyes. Pluto only barely passed muster as a planet when it was discovered in 1930. Over the intervening years its status as a planet was called into question again and again and again, especially with the discovery of other dwarf planets, like Ceres, Eris, Haumea, and Makemake (they ran out of Roman avodah zoras and started using ones from different cultures). By the time Neil DeGrasse Tyson and the NYC Museum of Natural History Hayden Planetarium decided to get rid of it in 2000, its status as a planet hung by a thread. The decision of the International Astronomical Society five years later was only the last nail in the coffin. So if you’re going to insist that Pluto is a planet, start learning a new mnemonic. Maybe “My Very Educated Mother Can Just Sell Umbrellas, Not Party Hats However Magnificent.”
