Artificial earth satellites – Spacecraft launched into orbit around the Earth are called artificial Earth satellites – ISS. To solve various tasks, satellites use different equipment. It allows you to make measurements, transmit information and navigate on land vehicles, as well as monitor the Earth for various needs.
The satellite can often be seen with the naked eye (see Radiation receiver, eye) in the form of dots moving rapidly against the background of the starry sky. Unlike airplanes, which are illuminated in the form of colored and flashing beacons, the ISS have a silvery or slightly yellowish sheen, which is a reflection of sunlight. At times, the brightness of the satellite changes when it turns to the observer from different sides. It is often possible to observe a phenomenon when, at the entrance of the satellite into the shadow of the Earth, it seems to “go out”.
