I think you might mean : Why doesn't Mars fall into the Sun?

That's a fair question.

The answer is that Mars is in a stable orbit around the Sun. So the

Sun's gravitational attraction is exactly "used up" keeping Mars in

orbit. A force is needed to keep a planet in orbit, otherwise it would

fly off into space because of its momentum.
