A satellite is an object that orbits a planet or celestial body. In the context of Earth, satellites can be natural, like the Moon, or artificial, created by humans for various purposes. These artificial satellites are used for communication, weather monitoring, navigation, and scientific research. Artificial satellites are equipped with technology that allows them to transmit data back to Earth. They play a crucial role in modern life, enabling services such as GPS, television broadcasting, and internet connectivity. The development of satellites has significantly advanced our understanding of space and improved global communication.
