Why cant a satellite in orbit around earth cant fall into earth because?

because of the gravity in our solar system. The sun keeps us (the earth) in its gravity. And we keep the satellite in our gravity. And it works like stone in thread and if we rotate it then stone will be at the other end of thread and will keep surrounding you.

∙ 12y agoSatellites in orbit around Earth are in a continuous fall toward Earth, but because Earth is curved they travel around it. In other words, a satellite is a falling projectile that keeps missing the ground.

∙ 14y agoIt may sound strange, but gravity stops the object from falling to earth, because by the time the force of gravity has pulled the object in a certain direction, the Earth has moved away from that point, pulling it in an endless loop around and around.
Put simply, the object is falling toward Earth, which is always changing location, and the satellite keeps changing its direction to find Earth. Sadly, by the time the satellite gets there, Earth is gone, and is pulling somewhere else.
(BTW, centripetal force isn't actually real, it doesn't exist. So be wary of those who say its the centripetal force. It only exists because we imagine it to exist.)

∙ 11y agoHere's one qualitative way to think about it:
The satellite IS falling toward the Earth. But, as you may recall, the Earth is round
like a ball, and the surface of the Earth curves away from the satellite just as fast
as the satellite falls. So the satellite just keeps falling around the Earth, and never
gets any closer to the surface.

plus comets and asteroids stay in solar orbit ... because that's the way gravity works.

Person sitting in an artificial satellite of the earth have?
... a feeling as if his weight is zero, because he is constantly falling around the Earth in the satellite's orbit..
Why is the moon called a natural satellite of the earth?
Because it is a satellite - it stays in orbit around Earth. And it is natural - meaning not made by humans.
The moon orbiting earth is an example of a what satellite?
A moon is a natural satellite, as opposed to an artificial satellite, which is a man-made object in orbit.
How orbital speed of a satellite depends on its radius?
The larger the orbit, the longer the period of revolution. The Space Shuttle, when it is in orbit, revolves once around the earth in about 90 minutes. The moon ... and any other satellite at a distance of about a quarter million miles from earth ... takes about 27 days to revolve once around the earth.
Earth moves in a elliptical orbit around the?
The Earth follows a (slightly) elliptical orbit around the Sun.
How is the moon a satellite to earth?
A satellite is any object that is in orbit around another object. The moon is a natural satellite of the Earth because it orbits around the Earth.

Is the earth's natural satellite the sun?
no, the moon is the Earths natural satellite, the moon is in orbit around the Earth. The whole Earth/Moon system is then in orbit around the sun.
Does a satellite revolve in orbit around Earth?
Yes.
How is a satellite kept in orbit around the earth?
Gravity
The path of a satellite around earth is called its?
orbit
How is a satellite maintained in orbit around earth?
gravity
How satellites stay in orbit?
The reason that satellites stay in orbit around Earth is because of two factors. Velocity and the gravitational pull between the satellite and the Earth.
Is the work is done when satellite orbits around the earth?
No because it stays in orbit and takes pictures of the ever changing earth.
Why is the moon called a satellite of earth?
A satellite is an object that orbits around a planet or body in space. There are artificial satellites and natural satellites. An artificial satellite is an object, like a space station, that has been set into orbit around a planet by humans. A natural satellite naturally finds its way into close orbit around a planet, like the moon naturally orbits the Earth.
What is the speed of a satellite that moves in an eliptical orbit around the earth?
If a satellite is in an elliptical orbit around the Earth, the Earth will be at one of the focii. The speed of the satellite will then constantly be changing. It will move the fastest when it is nearest to the Earth (perigee) and slowest when it is furthest away (apogee).
