The planets experience two types of forces:
Gravitational forces pulling them towards the sun. This keeps the planets from flying off into space.
Centrifugal forces, pulling the planets away from the center of rotation. This keeps them from falling into the sun.
The perfect balance of these two forces keeps our planets rotating exactly how they are.
Comment: I think that even scientists sometimes use the idea of "centrifugal
force", for convenience. However it's really not a "force", but an "effect".
You get a similar thing when they talk about the "Coriolis force". These things are sometimes called "fictitious forces".

∙ 11y agoThey don't crash into the Sun because of their inertia. Their inertia keeps them from crashing into the Sun.
All the Sun's gravitational force is needed just to hold the planets in orbit.
If it were not for the Sun's gravity the planets would "fly off" into space, in a straight line.
It's a bit like swinging something around on a string. You have to keep pulling just to keep the object circling. If you let go, the object will "fly away" from you.

∙ 11y agoAn orbiting object is in equilibrium between flying straight out of the solar system and falling into the sun. The fact that it is always falling toward the sun keeps it from flying off, and the fact that the law of inertia is trying to keep it going in a straight path at a constant velocity keeps it from falling into the sun.

ANOTHER VIEWPOINT: A SCIENTIST WOULD SAY THAT THE PLANET HAS "INERTIA". ITS
VELOCITY COMBINED WITH THE GRAVITY OF THE SUN MAKES
THE PLANET GO IN AN A ORBIT AROUND THE SUN INSTEAD OF
FALLING INTO IT.

∙ 11y agoThis phenomenon is controlled by gravitational pull.
Large objects tend to have a large gravitational pull. Smaller objects are pulled in by large objects. The reason why planets are a steady distance from the sun is because they have a perfect amount of inward and outward pull.

Why do the 8 planets keep orbiting the sun?
The sun's gravity keeps them in orbit and prevents them from flying off into space. The planets travel quickly enough that they do not fall into the sun.
Why don't satellites in orbit fall to the ground why don't the fly off in space?
that is because the 0 gravity keeps it in space and the orbit brings them around without knocking them down or anywhere else
What was the name of the first space shuttle to fly in space?
The first Space Shuttle, named Columbia, took off into space on April 12, 1981.
Why are planets visible?
There is enough sunlight reflecting off them and reaching our eyes.
Why does a satellite not fly off into space from the earth's atmosphere?
because the earth's gravity keeps it in place
Why don't planets fly off into space?
its because of the gravity coming from the sun
Why don't satellies in orbit fall to the ground why don't they fly off into space?
Because it have some gravity from space.
Why does the earth not fly off into space?
Because the suns orbit holds the earth and all of the other planets in place.
Why does not the Earth fly off into outer space?
Because the suns orbit holds the earth and all of the other planets in place.
Why do the planets not fall into the sun or fly off into space?
This phenomenon is controlled by gravitational pull. Large objects tend to have a large gravitational pull. Smaller objects are pulled in by large objects. The reason why planets are a steady distance from the sun is because they have a perfect amount of inward and outward pull.
Why do the planets stay in the same orbit the whole time?
Because the gravitational pull of the Sun - keeps them there ! The planets are always trying to fly out into space, but the outward pull of the planets is counteracted by the gravity the sun exerts on them. If the sun's gravity stopped - all the planets would zoom off into space !
Why do the 8 planets keep orbiting the sun?
The sun's gravity keeps them in orbit and prevents them from flying off into space. The planets travel quickly enough that they do not fall into the sun.
Would you fall off of Uranus?
No, like all planets (and most moons), uranus has enough gravity to prevent things from flying off into space.
How does the space shuttle fly?
It really doesn't fly, on lift off it is essentially a Rocket, on reentry it is a brick with wings, it more has a controlled fall back to earth than a flight..
What would happen to our solar system if there were no gravity?
The planets would fly off into space and lose their moons and atmospheres. The sun would explode from its enormous interior pressure.
Gravity is the reason that the planets stay in orbit around the sun?
It is half the reason, at least. Gravity is the force pulling the planets towards the sun, but they also have a velocity working perpendicular to it. With the velocity alone, the planets would fly off into space. With gravity alone, the planets would be pulled into the sun.
Can planets fall off there orbit?
scientists are still discovering
