Pluto

In the last few days, it became a hot topic whether Pluto remains as planet or not. Then it was decided that Pluto was excluded from planets in the solar system.
I felt fuss that was made about it was strange. Being Planet or not is decided just by humans who live in the earth that is small planet in the solar system.
Even if humans change definition of the universe or appellation, nothing changes in the universe.
By the way, textbooks makers and astronomic observatories become get busy with changing explanations about planets. Pluto, you won't be excluded from Disney characters, right?
