Satellite is an artificial object that is set up in orbit around the Earth or the Moon or any other planet as a means of collecting information or as a means of communication. Thousands of man-made satellites revolve around the Earth's orbit. Some of them collect photographs of different planets, some also help to predict weather weather forecasts, including the effects of various natural disasters.

Because of the satellite's bird eye view (seen on many of the ground surface like birds), we see a large part of the Earth from above. Because of this, satellite can collect faster and accurate data than any device installed on the surface of the Earth. Even in observation of objects, the satellite plays a more effective role than the telescope.
