    Planets which are present in Goldilocks zone with proper chemical ingredients should be habitable. And some planets which are away from the Goldilocks zone have frozen water ice as it's very cold so far away from the star. Can we organize an explosion on the side of the planet away from the star, strong enough, so as to push it closer towards the star into the Goldilocks zone and if we can, is there possibility that the disturbed planetary system will come to a stable state and remain there?

    Are you referring to our solar system (ex: changing the orbit of Mars?) or other solar systems (with potential for have a massive star or 2 stars)?
    Im no scientist but in my opinion it would require insanely massive efforts over many years just to nudge a planet in such a way that having it reach the desired orbit a million years later would be considered a success. (I dont know what type of apocalyptic planetary event or engineering feat would nudge a Mars sized planet by 1 km per year, but it it were achieve it might take over a hundred million years to reach a near earth orbit).
    I imagine it would be easier to colonize by building networks of giant city-sized bio-domes over the span of decades and centuries (on a greater selection of planets and moons) than trying to blast a specific planet into a different specific orbit and waiting for conditions to support earth-adapted life.

    Any explosion large enough to substantially shift the planetary orbit would destroy it in the process. That's not how you move planets or asteroids. Gentle and slow is the way to go. And precise.

    Thanks for your reply guys. I read a new paper article some time ago which said that recent Chile earthquake reduced earths rotation by some nanoseconds. So I thought if you could give enough force, you could change a planet's orbit.

    Orbits don't really work like that. There's a lot of energy (angular momentum) in an orbiting body.

    Regarding the change in the earth's rotation by large quakes, that's caused by a change in the distribution of bass; the "spinning ice skater" effect.

    the few seconds it took to realize there was a typo were confusing

    (Brad Paisley song "I'm going miss her" goes through head)

    From what I understand Mars is in the Goldilocks zone already...its problem was insufficient mass. It will certainly be in the Golidlocks zone a billion or so years from now but probably will be pretty low on volitiles.

    If Venus (as it is today) was (magically) teleported in the current orbit of Mars, I guess it would cool down over time, but after a thousand years, would it be (speculating) colder than the earth or still hotter because of gases?

    There is an interesting new hypothesis about planet formation in habitable zones,

    generated by the proto-planet itself. You can read the article as free PDF here:
