The term “satellite” usually refers to an artificial satellite, which is a man-made object that orbits the Earth (or another celestial body).
The question here is: what keeps the satellite from falling out of the sky?
Over the past half century, more than 2,500 satellites have followed in the footsteps of the first satellite into space. What helps them to stay aloft? It’s a delicate balance between the satellite’s speed and the gravitational pull.
Satellites also need to be adjusted regularly for smooth operation.
Basically, the satellite is constantly falling. But if traveling at the right speed, satellites will fall at the same rate that the Earth’s curve shifts away from them, meaning that instead of splashing out into space or plunging to Earth, they are still in orbit. Green Planet.
Satellites also need to be adjusted regularly for smooth operation. Earth’s gravity is stronger in some places, and satellites can also be pulled back by the Sun, Moon, and even Jupiter.
In addition to gravity, low-Earth orbit satellites such as the Hubble Space Telescope can also be deviated from orbit by atmospheric pull.
The satellite also has to constantly move skillfully to avoid space junk and other high-altitude objects.
