Could it potentially be an object orbiting around the cosmic center that just so happens to have an orbital path that crosses us?

I have to admit that astronomy is what caused me to change majors, but that's because I stopped going to class when the lesson was, "This is a terrestrial planet, it's rocky," and my first exam was like, "If it's 5:45pm in Tanzina on October 15th, how many degrees is the moon above the horizon?"

Had to do AM because it's below the horizon in the PM.

I really want you to know that I appreciate this.

Since the speed something is moving away is dependent on the distance, something billions of light years away is absolutely not going to be moving towards us, regardless of its local orbits.
