A satellite is an object that orbits around a larger celestial body, such as a planet or a star. Satellites can be natural, like the Moon orbiting Earth, or artificial, which are human-made objects launched into space to perform various functions.Artificial satellites serve a wide range of purposes, including communication, weather observation, navigation, scientific research, and military applications. They are equipped with various instruments and systems that allow them to fulfill their specific objectives.Communication satellites are among the most common types. They are placed in geostationary orbit, approximately 36,000 kilometers (22,000 miles) above the Earth’s equator. These satellites stay fixed relative to a specific location on the Earth’s surface, allowing them to provide constant communication coverage to a particular region.Weather satellites are designed to monitor and study weather patterns, climate changes, and atmospheric conditions. They provide valuable data used in weather forecasting, disaster management, and scientific research.
