Uranus
I don't know of any planet with exactly 21 known moons. The best answer is probably "Uranus" with 27 moons (natural satellites).
Saturn is the only planet that has 3 rings and 16 satellites .....
Jupiter, with 63 satellites.
Jupiter
Satellites, can either be natural satellites (for example; Earth's moon), or man made satellites (for example; communication satellites).

If a planet has a satellite, it de facto is orbiting the planet. In our solar system, Mercury and Venus do not have satellites, Earth has one, Mars two, Jupiter at least 60, as does Saturn. Uranus has 27, Neptune 13. Adn all of them orbit their planet.
You probably mean to ask about natural satellites as opposed to artificial satellites. In terms of neutrality, all satellites are neutral. In any event, the planet Jupiter has the most natural satellites, of any planet in our solar system. The planet Earth has the most artificial satellites.
i meant planet Earth has fewer because Earth has only 1 satellite and Uranus has 27 satellites.
