00:00What's the real reason that Pluto was a planet but isn't anymore?
00:04My hot take is that it never should have been, but I still love it.
00:07Hear me out.
00:07So once upon a time in 1930, there were eight planets.
00:10And then an observatory in Arizona spotted a new one.
00:13If you look back at the original reports, you'll see we thought it was the size of Earth or larger.
00:18So this was huge, but then over time estimates started to shrink and shrink and shrink.
00:23So by the time I was a kid, we knew that Pluto was smaller than the moon.
00:27And it was the ugly duckling of the planets because it also had this weird orbit.
00:30But it wasn't an asteroid, and it wasn't a moon, so...
00:34But then in 2005, we discovered these.
00:36Pluto's not alone.
00:38So finally, the International Astronomical Union officially revokes Pluto's planet status
00:43and said that all planets have to meet these three criteria.
00:46And the world lost their mind.
00:47I remember being devastated.
00:49But Pluto doesn't have to be a planet to be loved.
