A satellite is any object that orbits a larger celestial body, such as a planet or a moon. These objects can be naturally occurring, such as natural satellites (moons), or they can be artificially constructed technological devices placed into orbit. The physics governing these movements dictate that the object must maintain a precise velocity and altitude to remain in a stable path determined by the gravitational pull of the central body. Functionally, man-made satellites are deployed for various scientific and technological purposes, including remote sensing for Earth observation, transmitting global communication signals, providing navigation data, and conducting astrophysical measurements. These capabilities rely on sophisticated orbital mechanics and highly specialized equipment designed to operate reliably in the extreme vacuum and radiation environment of space.
