How many natural satellites does Earth have?
(A) 1
(B) 2
(C) 3
(D) 4

Hint:The object which revolves in orbit around any planet is known as satellites. So natural satellites are those satellites which already exist in the nature and role of humans for their generation is zero. The satellites made by humans are known as artificial satellites.

Complete step by step answer:
A large number of satellites revolve around the earth for communication and observation purposes. Generally, a satellite means a machine that is launched into space which revolves in orbit around the earth. For the communicational and observational purpose, this machine generates a communication system with the help of transmitter and receiver. But these satellites are man-made satellites, and they are produced to fulfill the human requirement, due to this reason these satellites are known as artificial satellites.
One other type of satellite apart from the artificial satellites is nature satellites. The natural satellite exists naturally in space. The natural satellites also produce some effects on the earth surface, but cannot be used for communication purposes. The natural satellite which automatically revolves around the earth and produces light on the earth's surface is the moon. So, the moon is considered as the only natural satellite of the earth.
Therefore, the earth has only one natural satellite and option (A) is correct.

Note:Some additional information about the earth natural satellite is that during the revolution, the moon can travel at 2288 miles per hour and the moon takes almost 27.3 days to travel around the earth one time. It is the fifth-largest solar satellite of the solar system.
