i don't know whether its inertia or centrifugal force, i think inertia

Gravity could be the major cause but there are others.
check the below amazing video, it is worthy to watch those 24 minutes. this is amazing!!!

Gerino's got it.
The Earth's speed around the Sun is such that centrifugal force just balances out gravity from the Sun. For us to move away, we'd need to gain speed (to increase centrifugal force) or to reduce gravity from the Sun.
I have no idea how the gravity from the Sun could be reduced.
In order to increase our speed, we'd need a force ( F = m a); given the mass of Earth, it would have to be a gigantic, large force. In the absence of such a force, inertia keeps us going at our constant, safe speed.

Gravity. Read all about centrifugal forve/accelleration in any undergraduate Physics book. And, while you're at it, try to learn a bit about inertia as well.

Moving away? Gravitational force. Centrifugal force keeps us from smashing into the Sol (our sun).

Gravitational Force of Sun keeps earth from moving away from it.

Once again to finish the answer ,it is simply gravitational pull that keep us from haulling in towards the sun or any other planets. My answer to you

Gravity. Not just a good idea: it's the Law.
