How would you identify space station from earth with naked eye?

You can identify the International Space Station (ISS) from Earth with the naked eye by looking for a fast-moving bright light steadily crossing the sky. ISS appears as a very bright star moving steadily across the sky, typically taking a few minutes to pass overhead. You can use websites or apps like spotthestation.NASA.gov to find out when and where to look for the ISS from your location.
