There once was a 9th planet in our solar system. Its name was Pluto, and it was a "fact" that it was a planet...until it wasn't. Join us as we explore whether Pluto should still be a planet.

The Life and Times Of Pluto
This section details Pluto's discovery in 1930, its classification as a planet, and the subsequent observations that challenged its planetary status due to its size and orbit, which are similar to objects found in the Kuiper belt.

The Fall Of Pluto
The reclassification of Pluto in 2006 by the International Astronomical Union (IAU) is discussed, which resulted from new criteria for defining planets. This led to Pluto being categorized as a dwarf planet.

Should We Really Care If It's A Planet Or Not?
The video explores the implications of Pluto's status change and debates the significance of whether Pluto is called a planet or not, arguing that it has cultural and educational impacts.

Reason #1 - Why Change History And Schoolbooks?
Arguments against redefining Pluto focus on the educational and historical consistency of its status as a planet, discussing the emotional and practical implications of such a change.

Reason #2 - There Are Scientists Who Still Debate Pluto Is A Planet
The ongoing scientific debate over Pluto's planetary status is highlighted, with references to scientists who oppose the IAU's reclassification based on its physical characteristics.

Reason #3 - There Are More Accurate Ways To Define A Planet
Proposals for a new definition of a planet that could include Pluto are discussed, suggesting that the current IAU definition is inadequate and overly restrictive.

Reason #4 - Those Asteroids In The Belt Aren't Exactly Like Pluto
This part argues that the objects in the Kuiper belt, which are similar in size or larger than Pluto, do not share its complex geological history, which supports Pluto's planetary status.

Save Pluto
The video concludes with a call to action for reconsidering Pluto's demotion, emphasizing the emotional and scientific reasons to restore its status as a planet.
