Pluto still is considered an actual planet in the solar system by everyone born in the 20th century.

All these definitions are conventional garbage anyways. There’s very little in common between rocky planets and gas giants. Ganymede is bigger than Mercury by volume. If Pluto is a planet, then so is Charon because their barycenter is outside Pluto. Etc etc etc.

>>16554510
>Zoomer (born in 2000) here. Is it true that Pluto used to be considered an actual planet in the solar system?
Yes, and for a brief time, the asteroids, Vesta, Juno, Pallas, and Ceres were also considered planets.
We had to adopt a stricter definition or pretend that our solar system has about 800 "planets.">>16554514
>Pluto still is considered an actual planet in the solar system by everyone born in the 20th century.
I was born in the 20th century and I do not agree that Pluto is a planet.

>>16554518
>All these definitions are conventional garbage anyways
Yes, so anyone born in the 20th century should default to what they've known since childhood.

>>16554540
You should be consistent at the very least. So if you consider Pluto a planet, then all the other meme rocks in the Kuiper belt are planets. And arguably is Charon as well. So the answer can be anything but 9.

>>16554543
I don't base my definition of a planet on some arbitrary set of criteria. I base it on what I was taught since childhood. I don't care if there's some rock out there 1000 times the size of pluto. Pluto is a planet, and that big rock is just a rock. It's all arbitrary bullshit anyway, so my arbitrary bullshit is just as valid as yours. You and your panel of scientists who decided Pluto isn't a planet can fuck off.

>>16554552
So if you were taught that pigs fly then that's what you'd continue to think? You sound like the perfect golem.

>>16554555
It's more like I was taught birds fly, and then biologists randomly decided
>ackshully those are classified as reptiles now

>>16554510
"planets" is an archaic concept from when we only had naked eye observations of the sky.

>>16554572
>Pluto discovered in 1930
>I'm pretty sure those were "boomers."
While we're on the subject of people who mindlessly group things together that aren't actually the same...

>>16554560
And what exactly prevents birds from flying if they're classified as reptiles? Do they get sad from the news?

yeah, haha, it was pretty fake and gay, am i right?

zoomer born 2001 and i remember learning about the discovery of the "tenth planet" eris in preschool and subsequent demotion of pluto

>>16554552
You were taught a definition that was based on an arbitrary set of criteria

>>16554510
If you use the only definition that made Pluto a planet then there are ~110 planets.

>>16554722
>You were taught a definition that was based on an arbitrary set of criteria

No shit. And the new definition is arbitrary. Since it's all arbitrary, I'll go with what I was taught my whole life and what I have nostalgia for. Let's not pretend there's any science or rigor at play here. My fee fees are just as valid as any arbititrary criteria some panel of astronomer bureaucrats come up with.

>>16554510
>muh planet
It's Reddit garbage anyway.
This nigga got it right: >>16554518

In third grade, I made a model of the solar system and that included Pluto as a planet. Our science teacher, Ms. Rodriguez, said my model was the best and the entire class had to applaud when I presented it. Literally everyone clapped but not a meme. It was the best day of my life and no eggheads are going to take away my lived experience. Pluto is a planet and always will be.

>>16555022
Nah I like their definition more than yours

>>16554510
yes with alongside your mom before she too got reclassified

2000 is not zoomer

>>16554510
Planets should be defined as orbiting the Sun (not a moon) and having a genuine atmosphere.. not just the melting ice of a comet.

PLUTO is a planet.

>>16554514
'92 here. It's a dwarf planet.

>>16554514
/Thread

a planet is a big ball in space that isn't and was never a star.

Big Planet fears Pluto's potential.

>>16554514
Correct. Science by committee is for retards.
If it's spherical in space and not a star: it's a planet. Yes, the Moon is a planet and the Earth/Moon system is a dual planet system.

Cope.

Seeth.

this description implies that moons are also planets. it's not that simple

>>16554510
I was born in 2003 and remember books talking about it as a planet, how do you not know about this?

>>16556996
It is that simple.
The IAU version is overly complicated and retarded. If it's spherical in space and not a star it's a planet.

What it orbits doesn't matter. The IAU version is overly complicated and is as useless as the IAU.

>>16554510
Pluto orbits the Sun & has a genuine atmosphere..
Definitely a planet
