Since my childhood I`ve always learned that pluto was one of the 9 planets on our solar system, but then, few years ago, Pluto was "removed" from our solar system and instead of being a planet, it`s now a dwarf planet! For me, it`ll always be a planet, and I`ll always like him! you can`t just do that to pluto, he has feelings too!
And yes, I know you can`t see pluto on the image.
