As we saw in the previous Activity, the discovery of the KBOs has forced astronomers to think about Pluto’s place in the Solar System, since it now seems to be more the “king of the Kuiper Belt” rather than the 9 th planet in the Solar System.
This led to much debate, and then argument which reached fever pitch in early 1999, when friendships strained, internet headlines and editorials beefed up the story, and school children begged to have the little planet back.
Finally the IAU General Secretary had to issue a statement confirming that Pluto was indeed a planet (even though the term “planet” was not defined).
