The Earth would probably crack open like a giant pecan . Gravity would hold the pieces together for a time. The oceans would pour down the cracks produced and the geothermic heat would cause so much steam pressure that the earth would explode like a giant popcorn kernel. Earth's orbit would then consist of a giant belt of debris. Our Moon would gradually assume an erratic orbit and fling itself toward Venus with bad results occurring for the Venitians.
