cracking myself up thinking about the movement towards simplified forms in cave paintings

This is amazing I need one! It's beautiful I'll probably go and buy one now

I love subtle fandom shirts

Truely broken 💔

go on watch severance DO IT

severance is a good tv show go watch severance

Every now and then yt space channels will be like "Jupiter is not orbiting the sun!!" or "the Sun is not the center of the solar system!!"

Those statements are true but worded clickbaityly.

Technically speaking nothing in Solar System orbits the Sun. What they are orbiting is called the solar system barycenter (SSB).

A barycenter is an imaginary point in space where the gravitational force of 2 or more bodies cancel each other out.

The simplest example is the Pluto-Charon system.

See this animation for example. You can see Pluto seems to be orbiting "nothing", but that nothing is called a barycenter, where gravity of Pluto and Charon cancel out. If you were to sit in this "nothing", gravity from Pluto and Charon will pull on you equally.

This is true for any systems with 2 bodies or more. Earth-Moon system is not exempt. However, we don't perceive the Earth and the Moon as "orbiting each other", because the barycenter of both bodies is well inside Earth. The greater the mass difference, the deeper the barycenter is located inside the more massive body.

And yes, this does apply to the entire Solar System. But not just the planets, the dwarf planets, the asteroids, and comets. The Sun is also orbiting around a barycenter, the solar system barycenter (SSB) I mentioned earlier.

Like the Earth-Moon system, the SSB is very very deep within the Sun. Extremely deep, because the Sun accounts for 99.86% of the entire mass of the solar system. Remember that the greater the mass difference, the barycenter is located deeper inside the more massive object.

In fact the SSB is constantly changing as all the 8 planets, dwarf planets, asteroids and comets orbit the Sun. But again the Sun takes up 99.86% the mass of the entire solar system so the change is so minuscule and so insignificant.

This concept of barycenter is often not taught in school grade science, especially the "Sun is not the center of the solar system" part. Because the SSB is so deep within the Sun that it's not a big deal in the first place.

It's easier to just comprehend and digest that the Sun is the center of solar system.
