That's Why Pluto Is Not a Planet Anymore

If you were in elementary school before 2006, there's a good chance you had to memorize the order of the 9 planets in our solar system; Mercury, Venus, Earth, Mars, Jupiter, Saturn, URinus—also pronounced UrANUS, and finally Neptune, and Pluto. Now, if you're currently in elementary school, you might be saying, "Wait, there were nine planets?”

So, what happened to Pluto? It’s not like it’s gone anywhere. It’s still out there on the edge of the solar system, as cold and far away as ever, so what changed?

SUMMARY:
-Pluto hasn't changed, but our understanding of it has. We know way more about space than we did one hundred years ago.
-From the age of Galileo to the nineteenth century, planet referred to any object orbiting the Sun. So astronomers kept finding countless planets.
-We know that Pluto is only one 459th the size of planet Earth, making it smaller than the moon and only about twice the size of the former planet Ceres.
- Charon may be smaller than Pluto, but not that much smaller. One half the diameter might seem like a big difference, but not compared to the differences in size between the other planets and their moons.
-While Eris is slightly smaller than Pluto, initial measurements placed it as somewhat more massive. This added one more strike against Pluto’s status as a planet.
-First, a planet must orbit the Sun. Number two is that the object must be a sphere, or at least nearly so. Pluto checks the first two boxes but runs into trouble with number three, which says a planet must have "cleared the neighborhood" around it.
-Scientists who disagree with the IAU’s ruling and want to call Pluto a planet once more propose that any object with enough mass to maintain a spherical, or nearly spherical, shape would qualify as a planet.

Do you think Pluto should be a planet, or it's right where it belongs?

[rylsahmad]

If you ever depressed of being kicked out from your friends and family just remember pluto. You are not alone.

Science is truly interesting, only my teachers then made it boring.

[GenXfrom]

No offense to science but Pluto will always be a planet in my heart. 💯❤️

[DR_OID]

Pluto still holds it's heart and continues to show it to the universe. Pluto loves you. we love Pluto. Some of us call it a planet to keep it happy.

Me: Pluto why aren't you a planet?

Pluto: Ask NASA man. 😕

[ThePhobosAnomally]

There are rummors that Pluto stopped orbiting the sun for a while, when its clasification of a planet was demoted. In my heart Pluto is a planet. One of the coolest ones, actually.

[coolguyx]

When I was in Elementary school that was after 2006 and we still considered it a planet

[simerpreet]

Humans: Pluto is not a planet.

Pluto: What’s a human?

[pluto]

Thanks guys for all the supporting and loving comments, love you guys too

[DjurrenArt]

Calling Pluto a dwarf planet is kind of a back-handed compliment with a generous helping of salt.

[misuki]

Me: Pluto is a planet in another nation!

Friend: What nation?

Me: My imagination- 😢

[Apaleutos]

"- George tell me the planets by order:
- Me: "Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto".

Memories from 1990!

[androkguz]

I tend to agree with the scientist who propose we include Pluto AND Ceres (and Ganimede and Luna) in the definition of planets.
I would of course add "Can't be so massive it makes self sustained nuclear fusion"

Natural satellites would continue to be satellites. Now lots of satellites would also be planets

But whatever

[omegazoo]

You’re still a Planet to me, Pluto-Kun

[unknown-ncic]

Other planets: *runs*
Pluto: can I come :(
earth: NO
other planets: oh come on man
Neptune and Uranus: you can come Pluto
NASA: NO!!!!

[satoruswift]

is bright side even a genius or is he wise?!




P.S Whoever reads this, Have a great day! and may God bless you!

Pluto: "(sarcasticaly) Oh no, humans demoted me! What am I gonna do now...and why am I talking in English or talking in the first place?"
