A satellite is a man-made object that orbits around a celestial body, such as the Earth. It is typically used for various purposes, including communication, weather monitoring, navigation, scientific research, and surveillance. Satellites are equipped with instruments and sensors to collect data and transmit it back to Earth. They play a crucial role in modern technology, enabling global communication networks, accurate weather forecasting, and mapping of the Earth's surface. Satellites can be classified into different types, including geostationary, polar-orbiting, and low-Earth orbit satellites, each serving specific functions based on their orbits and capabilities.
