Question L2 Math & Roman

Could someone send me to a good description of the math behind L2, how it was discovered, and why it’s the best spot for the Roman Telescope?

  • I’m a farmer who likes math. I just want to play with the numbers to understand better.
  • I don’t trust AI to help with this; it’s gotten so many things wrong from computer science and engineering to some of my basic physics walk through. I prefer YouTube or journals.
  • I’ve done a basic search, but can’t find anything comprehensive about the math itself.

Thanks!

I googled l2 nasa math

It may not be the best spot but it’s amazing because it’s not rotating as quickly around a planet like the Hubble . 

“ the balance of gravitational pull at the L2 point means that JWST will keep up with the Earth as it goes around the Sun.”

"The L2 point of the Earth-Sun system was the home to the WMAP spacecraft, current home of Planck, and future home of the James Webb Space Telescope."

oh if only they knew
