Like satellites, the International Space Station (ISS) is in a constant orbit around the Earth. It is only visible after dark and when the sky is clear. It can appear as a very bright star, or sometimes numerous white/yellow lights in close proximity to one another. It’s path never changes so it is possible to predict when it will appear and at which location in the sky.
