Solid light same brightness as stars high in atmosphere or space moving north to south across Utah.

It was a clear night sky and I could see multiple stars. I saw a point of light about the same brightness as the surrounding stars but I noticed it was moving relative to the stars. From north north east to south southwest. It's speed appeared similar to a satellite and it was clearly far away but also very bright relatively. Once it reached about a 45 degree angle from my perspective it was no longer visible. It was a smooth flyby at a constant pace but how do I confirm if it was a satellite? Photos I have are interesting. They all show 3 points of light for this object. Could be from the image processing its movement but I don't know.
