The ISS and other satellites
Your meteor watch will also reveal many human-made stars
Through the night you will regularly see a point of light moving slowly across the sky. This will be one of the thousands of artificial satellites orbiting the Earth. Some will appear as bright as the stars of the Plough, others will be so faint you will barely see them and some might flare briefly, becoming strikingly bright before fading from view.
The International Space Station (ISS) can appear very bright in the sky sometimes, but it won’t be visible during the Perseids. If you see a number of satellites moving across the sky in a trail like railway carriages, they will be some of the many hundreds of SpaceX Starlink satellites now in orbit. Many professional astronomers are greatly concerned that as these satellites fill the sky they will ruin their work, while amateurs are frustrated by their impact on astrophotography and the natural beauty of the heavens.
