Correct.

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

I mean, sure, but that'd be like saying I'm pulling the earth towards me when I jump.

Pluto and it's biggest moon Charon about for the very center outside of each other. This means that you could build a space elevator directly between the surface of each of them and it would rotate around that point since they're also tightly locked.

Asteroids everything does to some degree even if miniscule I'd assume.

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

Well, while we are being 'that guy', factoid is one of those words which has changed its meaning by being used wrongly for so long that the original meaning has all but vanished.

A factoid is technically supposed to be something resembling fact, but not actual fact. (The Greek suffix '-oid' normally being used for that purpose, like in paranoid, "like knowledge" or asteroid, "like a star").

The best thing about factoid, is that factoid is now a factoid. Because it resembles what it is not lol...

Anyway, nowadays, you are allowed to use it the way you did, at least in the descriptivist world view. The prescriptivists may disagree, however. And those people are often 'that guy' ;)

Well, now I want to know if there's a regular schedule to the Jupiter-Sun barycenter being in or outside of the Sun, and how we can schedule holidays around it.

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

Here’s an animation

Like a brick in a washing machine

The link in your post links to a different image. Was that on purpose?

I wish that was updated for the current year (and beyond) It's important to know when giving OP's statement whether it's outside the sun at the moment

Orbiting a point within the sun is still orbiting the sun.

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.

I was going to complain about the use of "barycenter" instead of the more commonly known "center of mass". But after some searching, I guess barycenter is more obscure because it's more specific. I'm ok with that.

All the solar system matter contributes to an object's orbital center but that's constantly moving as the system moves.

I think (?) most planets have their barycenter inside the sun's surface

The gravitational pull of system matter pales in comparison to the sun so you don't need to consider it for amateur purposes.

You can try KSP (Vanilla) versus Kopernicus mod if you want to feel the difference.

Also called n-body

Technically speaking, no celestial body in our solar system orbits around a single point. The barycenter thing only works with two bodies. When there are more than two bodies, such as in our solar system, the orbits become chaotic. Granted, the influence between planets is small, so they all appear to orbit their barycenters with the sun, but there are small perturbations to the orbits caused by the locations and masses of all the other bodies in the solar system.

The barycenter is different for each planet-sun (or any two object) pairing.

The earth and moon have a barycenter which is beneath the surface of earth. Likewise, the barycenter of the sun-earth pair is below the surface of the sun

Edit:

The barycenter of our solar system orbits the center of our galaxy (again in a barycentric manner)

I guess they all orbit around the solar system's center of mass (negligibly affected by the universal CoM), but that CoM probably moves around as the planets themselves move.

Relative to what, you might ask? That depends who you're asking 😉

I think if it's to scale, Jupiter is way offscreen, like in another room in your building far away.

My dumb friend wants to know why adding more mass would make Jupiter smaller, can you help explain it to him?

no material object orbits another material object and they instead orbit their collective center of mass somewhere in space.

That’s exactly what happens. Why do you think this is incorrect?

I thought it was a like Jerryboree but for Barys, which I think makes way more sense.

Gravity always wins

For most bodies the barycenter, while not the same as the center of mass, is still inside the sun. This one isn't, making it notable

No, this is actually really relevant. This is part of the logic applied to labeling Pluto a dwarf planet. Pluto and it's moon do this, Earth and our moon do not. Yes, obviously the center of mass of the two isn't the exact center of the earth but it's still within the earth.
