B Correct answer
Explanation

A natural satellite is any celestial body in space that orbits around a larger body. Moons are called natural satellites because they orbit planets.  

Satellites that are made by people and launched into orbit using rockets are called artificial satellites. There are thousands of artificial satellites orbiting the Earth.

The inner planets, Mercury and Venus have no natural satellites; Earth has one large natural satellite, known as the Moon; and Mars has two tiny natural satellites, Phobos and Deimos.

Other outer planets also have many natural satellites.
