Hey kids, I don’t mean to spoil the party, but that article says that a public debate was held at Harvard and the audience, after hearing the different arguments, voted in favour of Pluto being a planet. Nowhere does it say that the IAU, NASA or any other space agency or organisation have officially recognized Pluto as a grown up planet. It does, however, make an interesting semantic argument. Pluto is classified as a dwarf planet along with dozens of other rock lumps flying around out there with it. When we use the word dwarf as a prefix in other instances in English it describes specification, not exclusion. I.e. A dwarf rabbit is still a rabbit and a dwarf fruit tree is still a fruit tree. By those semantics Pluto is still a planet, along with Eris and all it’s other miniature friends.
