What is the name of the star orbiting the planet?
Picture display: Introduction:
Satellite refers to a natural celestial body that runs around the planet and periodically in a closed orbit. Satellites can also be called satellites in general. Man-made satellites are devices built by human beings, which are launched into space by spacecraft such as rockets and space shuttles, and orbit around the earth or other planets like natural satellites.
With the continuous development of modern science and technology, mankind has developed a variety of artificial satellites, which, like natural satellites, are also orbiting planets (mostly the earth). The concept of artificial satellite may have started with 1870. The first artificial satellite officially put into orbit was Sputnik 1 launched by the former Soviet Union in 1957. Since then, thousands of planes have flown around the earth. Satellites have also been launched into orbit around Venus, Mars and the moon. Satellites are used in scientific research and have become indispensable tools in modern communication, weather forecast, earth resource exploration and military reconnaissance.
