Satellites

Definition

Satellites are objects that orbit a planet, moon, or other celestial bodies, either naturally or artificially. They play a crucial role in remote sensing by collecting data about planetary surfaces, atmospheres, and other characteristics, which can then be used for scientific research and exploration.
