What is a Satellite and why its important
A satellite is a moon, planet or machine that circles a planet or star. For instance, Earth is a satellite since it circles the sun. Generally, "satellite" alludes to a machine that is dispatched into space and moves around Earth or another body in space. Earth and the moon are instances of normal satellites.
A large number of fake, or man-made, satellites circle Earth. Some take photos of the planet that assist meteorologists with anticipating climate and track storms. Some take pictures of different planets, the sun, dark openings, dim matter or distant systems. These photos assist researchers with bettering the close planetary system and universe.
Then again different satellites are utilized primarily for correspondences, for example, radiating TV signals and calls all throughout the planet. A gathering of in excess of 20 satellites make up the Global Positioning System, or GPS. In the event that you have a GPS beneficiary, these satellites can assist figure with trip your careful area.
Why Are Satellites Important?
The bird's-eye see that satellites have permits them to see enormous spaces of Earth at one time. This capacity implies satellites can gather more information, all the more rapidly, than instruments on the ground.
Satellites additionally can see into space better compared to telescopes at Earth's surface. That is on the grounds that satellites fly over the mists, residue and particles in the air that can hinder the view from ground level.
Prior to satellites, TV signals didn't go exceptionally far. Television flags just travel in straight lines. So they would rapidly trail off into space as opposed to following Earth's bend. Now and then mountains or tall structures would hinder them. Calls to distant spots were likewise an issue. Setting up phone wires over significant distances or submerged is troublesome and costs a great deal.
With satellites, TV signals and calls are sent vertical to a satellite. At that point, quickly, the satellite can send them back down to various areas on Earth.
