Diamond-shaped UFO passed by ISS on January 2018

On January 2018, a diamond-shaped UFO is passed by the International Space Station. This weird object was videotaped by NASA. What is it?

Scott C. Waring explains:

This diamond UFO was flashing as it passed by the international space station this week. Its white, much like the space station and when it lights up, its very visible in the background. The shape is like a diamond and it seems to be watching the space station, orbiting it if you will. This is a fantastic video made by Streetcap1 of Youtube. 100% evidence that aliens do exist.
