Jokes aside : being right for the wrong reasons is being wrong

[-] unwarlikeExtortion@lemmy.ml 2 points 6 days ago

It's not wrong. The "common center" lies inside the Sun.

Therefore, the Sun orbits itself and the Earth orbits the Sun.

The Man-in-the-middle's statement is akin to the following :

2 = 3 thus, by multiplying both sides by 0, we get 0 = 0, which is true !

He said it's in the middle because 2 people disagreed, and he states that the truth lies always in she middle in these situations. which is false, exactly as false as 2 = 3

If we’re strict, being right is always being right. If we’re not strict, wouldn’t that imply that being wrong “for the right reasons” is being right?

I believe that's the same for every planet. And every moon. For every orbit.

Its just that the barycenter is inside the more massive object when one is much more massive than the other. Not that this makes much of a difference to anything.

Correct.

I also believe that one of the criteria for a binary planet is that the barycenter is outside either body. Like Pluto/Charon.

The barycenter is sometimes outside the diameter of the sun. Not always, and I believe not even usually.

Yes, today I'm being that guy. Still a cool factoid.

[-] bdonvr@thelemmy.club 38 points 1 week ago

I'm kinda stunned that it's EVER outside the sun.

The way this is phrased makes it sound like there's a certain threshold where this starts happening. That's not right. Even a grain of dust wouldn't orbit the sun, they still orbit their common barycenter. A less misleading way of phrasing would be that Jupiter is massive enough that the barycenter of it and the sun actually lies outside the sun, which is still a cool fun fact.

[-] BillBurBaggins@lemmy.world 36 points 1 week ago

I mean that's literally the point the image is trying to make. The last sentence says the point is outside the sun for Jupiter.

I don't think nitpicking the title achieves anything and it's not even misleading unless it's only taken in isolation.

[-] CheeseNoodle@lemmy.world 2 points 6 days ago

That's still not entierly mass dependant, the point is at a distance based on a ratio between the two masses, if Jupiter were closer to the sun then the point would be inside the sun. Its still impressively massive to pull the point outside of the sun at any functional distance but so could a grain of dust with sufficient distance and a big empty universe to prevent anything else from interupting things.
