Question

State whether the sentence is true(T) or false(F).
The earth is the only planet that has a natural satellite.
A. True
B. False

Answer 1

Hint: Satellite is a body that usually orbits around another celestial body in space. Satellites can be of two types, namely, natural and man-made satellites.

Complete answer: A natural satellite is any celestial body that orbits around a larger body and an example of a natural satellite is Moon. Satellites which can be made via way of means by human beings and released into orbit the usage of rockets are referred to as artificial or man-made satellites. There are hundreds of man-made satellites orbiting the Earth. Man-made satellites vary in different shapes and sizes.
The Moon is the only natural satellite of the planet earth and orbits around it. The time is taken by the Moon to complete one orbit around the earth in 27.3 days. Mars has two natural satellites, Phobos and Deimos. Phobos completes one orbit around Mars in 0.32 days. Jupiter consists of 4 natural satellites orbiting around it, namely, Io; Europa; Ganymede; and Callisto. Ganymede is considered to be the largest moon or natural satellite of the solar system. All planets in our solar system except Venus and Mercury have natural satellites called moons.

Thus, the correct answer is option (B).

Note: Satellites communicate through the use of radio waves to send alerts to the antennas at the Earth. The antennas then seize those alerts and process the records coming from those alerts. The information which is sent through these antennas includes scientific data, the condition of the satellite and where exactly the satellite is located.
