What if half a planet (not necessarily earth) was destroyed (not split)

Basically I want to know what would happen to a planet if half of it was destroyed using explosives, does the answer depend on the size/gravity of the planet and what would be the result on the environment and inhabitants.

Per the comments this is an earth-like, earth-sized planet and for the intents of the question the half of the planet just disappears.

Ok so almost all of my question has been answered but a small detail remains when the hemisphere that remains collapses must the resulting form be a regular sphere this is only sci-fi but can it form a I don't know a cube,pentagon or a weird irregular shape like that of a sea urchin and must the hemisphere even stabilize can it breakdown to chunks or form an asteroid belt like shape Updated: thanks alot guys from what I collected from your answers that it would be way more merciful if for e.g aliens destroyed the entire planet rather than the inhabitants live through that hell (I apologize in advance for the lame puns). I mean if your gonna do a job do it right don't stop halfway, don't take it halfheartedly and just because its all right doesn't mean its alright
