I understand the human urge to hold onto something that we’ve been taught and grown accustomed to. Pluto was labeled a Planet for about 76 years, and that is a difficult adjustment to make. That being said, Pluto is not a planet, and we only thought it was due to confusion about its size and it being unclear how many bodies similar to Pluto orbit our star. The Kuiper belt, an interesting disk of icy objects orbiting the Sun and the home of Pluto, threw scientists for a loop as it was discovered. While Pluto is the biggest object in the Kuiper belt, it is not alone, and the others were very near Pluto (at least in space terms). Pluto is not alone. Being part of the Kuiper belt, not much bigger than its other members (and dwarf planets), and being vastly smaller than our other planets, made it clear that Pluto is not like our other planets.
This does not mean Pluto is not cool, interesting, or worth studying. I hold a lot of care for and interest in this Kuiper belt body. Pluto is special in its own way. Being the 9th largest and 10th most massive object in our solar system is cool in its own right. Pluto is sometimes considered to be part of a binary system with its moon Charon, which has a diameter just over half of Pluto’s. This is because the center point for their orbits is not within either body, and they are both tidally locked. Pluto has an interesting icy surface and is the largest object to be that far from the Sun. Overall, Pluto is not a planet. Get over it and appreciate what actually makes Pluto interesting.
