Here's the breakdown:

* Satellite: A satellite is any object that orbits a celestial body. This includes natural satellites like moons, and artificial satellites like those we launch for communication, navigation, or scientific purposes.

* Space probe: A space probe is a spacecraft that is sent to explore other celestial bodies in space. They often travel far beyond Earth's orbit, to other planets, moons, asteroids, or comets.

So, while all space probes are satellites (because they orbit something), not all satellites are space probes.

Here's an analogy:

* Think of a car and a truck. A truck is a type of car, but not all cars are trucks.

* Similarly, a space probe is a type of satellite, but not all satellites are space probes.
