there isn't any resistance in space so if something is moving in space, it won't stop until some kind of resistance occurs. the gravitational force and the associated attraction keeps the asteroids moving in space.

If the objects approached the object that is pulling them in in the correct way from the correct angle they become caught in orbit around that larger object (In this case the Sun is the larger and the planets the smaller) That covers the why.
As to why gravity exists there are a number of theories and as they do not really pertain to this question you will have to ask again or look them up.
It is really not that simple of a question.

What keeps planets in orbit in your solar system?
Well, they are being attracted to the sun, but orbit fast enough that they don't fall into the Sun.
Why do the planets orbit the sun What is the shape of those orbits?
Planets orbit the sun because gravity keeps them from escaping, and momentum keeps them moving forward. The orbits are elliptical, which is like an oval.
What keeps us from floating off into the sky and keeps the planets in orbit around the sun?
gravity?
What does the sun's gravitational pull keep in orbit?
Planets, asteroids, meteors, comets, moons (which are also in orbit around their respective planets), dust particles, interplanetary gas.
What two forces work together to keep the planets in orbit around the sun?
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.
What keeps the planets in orbit about the sun?
The Sun has a powerful gravitational pull. This, combined with the velocities of the planets, keeps the planets in orbit.
What is the force that keeps planet in orbit?
the suns gravity keeps the planets in orbit
What does gravity have to do with planets?
It keeps them in orbit.
What keeps the planets in the solar system in orbit around the sun?
The Sun's strong gravity keeps all the planets in orbit around it.
What keeps the planets and moons in their orbit?
gravity
What keeps planets in elliptical orbits?
Gravity and velocity (inertia) keeps planets in orbit around suns.
What gives planets an orbit?
the gravitational pull from the sun keeps the planets and other small things in the orbit of the sun.(;
Why do you think the planets do not collid?
As the planets orbit the sun, its gravity keeps them from colliding
Why do you think planets do not collide?
As the planets orbit the sun, its gravity keeps them from colliding
What force keeps the planets and the Moon's to orbit?
Gravity
What force from the sun keeps the planets in their orbit?
Gravity
Does the sun's gravity keeps planets in orbit?
Yes, it does.
