A satellite is an object that orbits around a larger celestial body, such as a planet or a moon. In the context of space exploration, satellites are often artificial devices that are launched into orbit for various purposes, including communication, weather monitoring, navigation, and scientific research. Natural satellites, also known as moons, are naturally occurring celestial bodies that orbit planets. The most well-known example of a natural satellite is Earth’s Moon. Satellites can vary significantly in size, function, and type, ranging from large communication satellites that relay signals to and from Earth, to small satellites used for specific scientific or observational tasks.
