What would it be like if Earth was hit by some rogue planet?

I've been really curious about this. Just say for the sake of conversation, that all the wild theories about Earth being hit by a massive rogue planet were true..
What would it be like?
Would everything just go black, like turning off a light?
Would it be a massive firestorm that scorches the planet?

What would happen???

Theories?

It has an episode called rouge planet, it was pretty cool. Least I thought so.

I'd say with a massive rogue planet on its way towards us most would be dead before it got here. Gravity and all that.

Sorry, how do you mean?
Edit: I'm really curious what the physical reaction would be.

It would forever change earth, and her moon.

There was a movie about this not that long back... melancholia..

It was alright, pretty fair to say it'd go a lot like that movie portrays.

Would there even be an Earth in the aftermath?

My wife told me about that one, but I never got around to watching it.

The moon was created by one and mars was hit by another causing half its surface to be sheared off on one side.

So there are actually pretty good examples for us to look at..


If I'm right anything within 20% of the size of the earth would vaporize both planets.

Think about what would happen if the rotational path of the Earth around the Sun changed even 1 degree. Too close, runaway greenhouse and it becomes Venus. Too far and the glaciers return with a vengeance. All those would happen due to the distant effect of the gravitational disruption of any planetary sized body, before it even gets close enough to see with the naked eye. I'm not even going to add in the effect it would have on our Moon, which would likely crash into the Earth before any rouge planet.

Absolutely..would likely spit us into the sun or out past jupiter.

There wouldn't be people...

So everything would just go black then, all of a sudden.

Scary.

I've had many nightmares about the moon crashing to Earth.

Interesting!

Oh no we would be dead by asteroids or the earth moving out of its orbit long before impact.

Good point, hadn't really considered that.

Politics in general. And a lot of other things holding us back.

There is a movie about an asteroid smashing into the planet and in Australia they have 12 hours to live....It is kind of depressing, but VERY INTERESTING and GOOD.....here is a link about it.
