http://outskirtsbattledome.wikispaces.com/Gravitational+Binding+EnergyAccording to the science in these two links, moving Earth out of its normal orbit to Mars' requires a full order of magnitude more energy than destroying it.
Now while you can claim that science doesn't apply to comics, how else would you quantify it? Unless you have a scan of both Marvel and DC agreeing that busting a planet>moving it, you have no basis for your stance. I have basis for mine.
You are certainly correct in ascertaining that the minimum amount of energy needed to destroy a planet is less than the minimum amount needed to move it out of orbit. However what has been lost in the crossfire in this thread is that what Hulk and Betty did is beyond merely destroying a planet using the minimum amount of energy required. The planet, an army of mindless ones Armcheddon an amped fing fang foom, Bi Beast and Wendigo were all destroyed as well as a nearby moon being damaged from the residual shockwave of their physical impact miles above the planets surface. Hence the KE being released at the epicentre of their collision would be significantly significantly greater than the residual shockwave that wrecked the planet and thus considerably greater than the minimum amount of energy required to destroy one (on a smaller scale think koing a guy wiith a direct punch vs koing that same guy while punching a wall 100 metres away). There is a huge divergence between the two scenarios.
