What is the importance of satellite?
Why Are Satellites Important.
The bird’s-eye view that satellites have allows them to see large areas of Earth at one time.
This ability means satellites can collect more data, more quickly, than instruments on the ground.
Satellites also can see into space better than telescopes at Earth’s surface..
What is meant by artificial satellite?
An artificial satellite is an object that people have made and launched into orbit using rockets. There are currently over a thousand active satellites orbiting the Earth.
How many satellites are in space?
Number of launches to date (1957-2018) In the history of satellites, since the launch of first satellite Sputnik in 1957, around 8,378 satellites have been sent to space, as per the data by UNOOSA. These days there are 4.994 satellites in orbit, out of which only 7 are revolving around planets other than earth.

What would happen without satellites?
Likewise, without satellites over-the-air re-transmitters would no longer work, and this would have a huge impact on telephone and data transmissions, limiting them to land lines and submarine cables.
How many dead satellites are in space?
2,900 dead satellitesSince the start of the space age, more than 8,6o0 satellites have been placed into orbit. Of the approximately 4,700 of those still in orbit, only 1,800 are operational, leaving 2,900 dead satellites out there orbiting aimlessly and adding to the more than 21,000 objects currently being tracked and cataloged by NASA .
