I know that it's a dwarf planet now and it crossed over Neptune or something but I just don't know why they put it like that. I mean the Solar System changed now and some people still answers with 9 planets. For example: There could be a science test and if it asks the question "How many planets are there?" they would still answer 9 planets. I think that's unfair.
