Satellites are bright from reflected light and pretty close to the Earth (compared to stars), so they are very noticeable. Some, like the ISS, are also very noticeably moving across the sky, which draws your attention. Lastly, since they are brighter, they are more likely to be visible in situations where you have light pollution or the sky isn’t pitch black.
