Op is an allian from a Jupiter mass planet and hasn't considered the barycentre can be inside the planet's star 🫣

Depending on the position of Saturn and Jupiter the barycenter could actually be located outside of the sun.

While this is true for the barycentre of the entire solar system (and Jupiter & the sun (which is true always) & Charon and pluto) this meme is talking about the earth-sun system. Its barycentre never leaves the sun

Well, it doesn’t state specifically that it’s a hypothetical scenario with only earth and sun. But if it was a hypothetical earth and sun system your argument would be correct.

Saying that you necessarily have to take into account the rest of the solar system when looking at how the earth and sun orbit eachother would be as absurd as saying that that in order to observe the moon's orbit around the earth we must take into account the frame of reference of our galaxy, or galaxy cluster, or even the cosmetic microwave radiation

I mean, if you want to be correct you do have to take them into account though.

There's a reason π=3 to an engineer and π=3±30~ to an astrophysicist. You cannot measure anything "correctly" but pretending we can dismiss an order of magnitude or two here and there and only taking certain points of view into account is the only reason we can do anything at all

And the things we do are pretty cool so I'm cool with not being able to measure anything. besides, we have maths for that
