A body that revolves around a larger body in space can be referred to as a satellite. This term encompasses a wide range of objects, including moons, artificial satellites, and other celestial bodies that orbit a planet or a star.
When we consider the context of the question, it’s important to note that satellites can either be natural, such as moons that orbit planets, or human-made, like satellites used for communications, weather monitoring, and scientific observation. The key characteristic is the relationship of orbiting around a larger astronomical body.
Planets and comets are themselves larger bodies, and while moons are a specific type of satellite, they do not represent the broader category that is being asked in the question. Therefore, the term "satellite" accurately captures any astronomical entity that revolves around a larger body, making it the most appropriate choice.
