Satellites - Page 137

Satellites are objects that orbit a planet or celestial body, typically used for communication, navigation, observation, or scientific research. They can be natural, such as moons, or artificial, which are man-made and deployed into space for various purposes. Artificial satellites are equipped with technology to transmit and receive data, monitor environmental conditions, and provide services like global positioning and weather forecasting. They orbit at varying altitudes and inclinations, depending on their intended function, and can be classified into categories such as geostationary, low Earth orbit, and polar orbit satellites.
