How does a meteor or asteroid travel around the universe if there is no gravity?

If a meteor can reach earth or another planet traveling at tremendous speeds and fall by the gravity of that planet or earth,how or by what force does it travel?|||There is gravity everywhere, because gravity is "produced" by massive bodies, and the universe is filled with massive bodies. Gravity weakens at great distances from these bodies, but it never disappears.





Asteroids and the like move through space thanks to inertia鈥攌inetic energy they've acquired at some point in the past. Their trajectories are bent by gravitational fields produced by massive bodies such as planets and stars. As they move near to a star or planet, they are bent towards it. If they are moving fast enough, the pull of gravity from the other body can accelerate them (the other body loses some energy in turn). If they are moving slowly enough, they may be trapped by the gravitational field of the other body and enter an orbit, which they may maintain indefinitely.|||There is indeed gravity in space. Objects orbiting Earth are influenced by its gravity. The Earth is influenced by the sun's gravity, and the sun is influenced by the galaxy's gravity.





So asteroids are indeed influenced by gravity, and occasionally other forces.





The reason you can float around in space as though there was no gravity is because both you and your spaceship will probably have the same acceleration (unless of course the engine is turned on), so there's no "net" force inside the spaceship.|||It does indeed fall by the force of gravity. Gravity acts over enormous distances, farther than any other known force, many thousands or millions of times farther than the largest meteor orbit. Remember, gravity doesn't require a medium like air to travel through....all it requires is space.|||All bodies in the universe have gravity in themselves: it's a basic property of matter. All objects are influenced by gravity to some extent, usually by the most massive and nearest bodies to them.|||Meteors, asteroids, and anything else don't require any force at all to simply *travel.* A body in motion REMAINS in motion. Motion is the natural tendency of every physical body. Until acted upon by an outside force.|||The asteroids orbit the sun, there is plenty of gravity out by the asteroid belt and even out as far as pluto, otherwise pluto would not orbit the sun.|||There is gravity. The widespread opinion that "there is no gravity in space" is wrong.|||There is gravity.
