What is word satelite?

The word "satellite" is derived from the Latin word "satelles," which means "attendant". It refers to an artificial object orbiting around a planet or a celestial body. Satellites are used for various purposes, such as communication, navigation, weather forecasting, remote sensing, and astronomy. There are two types of satellites: natural satellites, like planets' moons, and artificial satellites built by humans. The first artificial satellite, Sputnik 1, was launched by the Soviet Union in 1957. Today, there are thousands of active and inactive artificial satellites orbiting Earth. Satellites transmit and receive signals, collect data, and provide valuable information about our planet and the universe. They have revolutionized the way we communicate, navigate, and understand the world around us.
