JWST isn’t going in circles, it’s orbiting the sun. If you look at it relative to that, then it looks more like a sine wave rather than going in circles. However from the perspective of the earth, it looks like it’s going in circles
Maybe gravitational push-pull between planets and moons… IDK, it might be some sweet spot they discovered where gravitational forces do weird things, lol 😂.
This. There’s 5 Legrange Points for every 2 body system. They’re specific points around the 2 bodys where the gravity “cancels out”. In this case the 2 body system is the Earth and the Sun. JWST is sitting a million miles from Earth at L2.
Dammit, I was feeling proud that my first thought on how this could work lined up with the explanation… But I had assumed L2 (didn’t stop to think about the label) was where I now see L1 to be. I can wrap my head around L1 just fine, but how the heck is L2 the same? Or the others for that matter? Gonna stare at this for a while…
If you understand gravity wells, think of L1/L2/L3 as the shape of a saddle. If you’re right in the middle of the saddle it’s a pretty stable orbit, but if you get too close to any of the edges you fall right out of it. L4 and L5 are like the peaks of a mountain.
Also worth pointing out that only L4 and L5 are stable, L1/L2/L3 are only metastable where they require a bit of maintenance to stay there.
Another fun fact about Legrange Points: There’s a group of asteroids called the Trojan Asteroids. There’s technically two groups of these since they’re stuck in L4 and L5 in the Sun/Jupiter system.
Have no idea how this works… there is no gravitational pull at the L2 point, it’s just an empty point in space 🤨.
There is gravitational pull, from both the Earth and the Sun. The JWST is orbiting the “earth-sun system” if you will.
You can read more about Lagrange points here.
So they solved the Three Body Problem?
It’s not really a three body problem. For that, the gravity of the JWST would have to affect the other two bodies, but its gravity is negligible.

You’re tell me bro. I need to research this more.

Ah, so that’s why we don’t put shit in L4 and 5 😂… things will bump in them once in a while 😂.
Yeah but it’s not at the L2 point, it’s spinning in a circle around L2.
Yes, my point exactly. There is no mass at the L2 point, so how can it spin around it.
Others explained it though, it makes sense now 👍.
PS: What are enbies 🤨?
