• Question: If people have already pushed poor Pluto out of the solar system, due to its size, do you think that people will push out other planets as well?

      Hey Devi333,

      I’m small too so I have a lot of empathy with Pluto!!

      Pluto is now officially a ‘dwarf planet’. As scientists learn more about the universe they sometimes have to reconsider how to group them and what makes a planet a planet. All the other planets are considered big enough to stay as planets for the moment but this could of course change in the future.

      Having said that I still think of Pluto as a planet in our solar system and I don’t think that’s going to change for me for a while 😉
