When you see a moving star, it is likely not a star at all, but rather a celestial object known as a satellite. Satellites are man-made objects that orbit the Earth, and they reflect sunlight, making them visible from the ground as moving points of light.
Satellites can appear like moving stars because they follow predictable paths across the night sky. They can be seen shortly after sunset or before sunrise when the sky is dark but the sunlight still reaches them at high altitudes. The movement of satellites is typically slower and steadier compared to other celestial objects, such as meteors, which appear as quick streaks across the sky.
There are various types of satellites, including communication satellites, weather satellites, and space telescopes, among others. The specific satellite you observe may depend on your location, time of observation, and the particular satellite's orbit. Websites and apps dedicated to satellite tracking can help identify the satellites visible from your location at a given time.
