An artificial satellite is a human-made object that is intentionally placed into orbit around a celestial body, typically the Earth. These satellites serve various purposes, including communication, weather monitoring, navigation, and scientific research. They can be found in different orbits, such as low Earth orbit (LEO) or geostationary orbit, depending on their function. Artificial satellites are equipped with instruments and technology that allow them to collect and transmit data back to Earth. They play a crucial role in modern life, enabling services like GPS, television broadcasting, and internet connectivity, while also contributing to advancements in fields like meteorology and astronomy.
