Update/Edit: Shout out to Rory Alsop and antlersoft who helped me.
How would we keep an object in L1 so it blocks light from getting to earth, or its in sight from earth during the day time? The goal isn't to block 100% of light getting to earth, just so the object's shadow doesn't miss earth.
I'm wondering if its possible for a satellite to follow earth around the sun while staying outside of its orbit. I wondering for the sake of space based solar infrastructure or just something constantly obstructing sunlight getting to earth.
I read something about objects in L4 or L5 zone taking about a year to orbit earth. I assume that might produce a similar result for what I'm looking for, and maybe its simpler? I'm having a hard time finding information about man made objects orbiting the sun, mostly because of mars trajectories articles.
Thanks!

The only stable points that orbit at the same speed as Earth are the L4 and L5 points, as you mention, but there are some unstable ones as well. See this pic from NASA:
L4 and L5 remain ahead of and behind the Earth, whereas L1, L2 and L3 are inherently unstable. From your question, I'd suggest L4 and L5 would be best suited, unless you really need proximity to Earth, in which case L2 could suit your needs.

Thank you, I think i understand Lagrangian points better now. Looking at the picture it looks like an object in L2 doesn't block light from earth. A quicker way to ask my question would be, "How to we keep an object in L1 so it blocks light from getting to earth".

Well, you'd also need to make it an incredibly large object... And you should probably check to see if there are any posts here already on maintaining L1-L3 orbits

Will do, also I should clarify it doesn't have to cast a shadow entirely over earth. Its shadow just has to reach earth.

You're on the right track looking up Lagrangian points, orbits where a small object can stay in the same relationship with two celestial bodies, one orbiting another. The one you are describing is the earth-sun L2 point, a point outside of earth's orbit around the sun. This Wikipedia page will tell you more.
