Answers
an artificial body placed in orbit round the earth or moon or another planet in order to collect information or for communication.
An object orbiting around the sun, earth or any other colossal body is known as a satellite. There are two major types of categorization when it comes down to satellites, one is natural and the other is man-made.
Some examples of natural satellites are planets, moons, and comets. Jupiter has 67 natural satellites. The earth has one permanent natural satellite, the moon we know, which causes the tides in the sea. Sometimes other objects (like asteroids) can enter into temporary orbits of the earth and become a natural satellite for a span.
Apart from these, the earth has many man-made satellites that are placed in the orbit and are used for different applications in communications and information gathering. As the term itself states, an artificial satellite is one that is put in our space by human efforts and follows the orbit of natural satellites.
Since they have a very large view field, they can collect data a lot faster than instruments that can be used at ground level. Apart from this, their view into space beyond earth is not blocked by clouds, dust, and other obscurities, due to which a satellite can view space a lot more efficiently than telescopes on earth.
