Could a rogue planet create a 100m tide on earth without catastrophically affecting it's orbit? If a sizable rouge planet hit one of the rocky planets such as Mars, large chunks of debris would come shooting out of the collision, a very high chance that a few pieces would land on Earth potentially creating another mass extinction; similarly to the other rocky planets such as Venus and Mercury. We’d rethink our energy sources, and try to pump out more greenhouse gases to warm the planet up a little.

Planets get ejected from their original solar systems for different reasons. The only way we could survive would be if we learned to live at the bottom of the ocean, next to deep-sea thermal vents that push out extremely hot water. It wouldn't be unprecedented. Because they don’t orbit a star closely (we’ll get back to that in a sec), they wouldn’t have a consistent light source, but radioactive decay or tectonic activity could provide heat. While they aren’t heated by an alien sun, it’s possible that they could retain some warmth from underground radioactivity or other processes. “We can rule out the planet having a star within about 8 astronomical units (the astronomical unit is the distance between the Earth and the Sun).” Unlike Earth, which is orbiting the Sun, there are billions of rogue planets roaming the Milky Way not bound to any host star. If a planet doesn’t belong to any star system, it’s considered a rogue planet. If the earth were flung out of the solar system, it would rapidly become far too cold for any unprotected life to survive on the surface. A rogue planet (also termed an interstellar, nomad, free-floating, unbound, orphan, wandering, starless, or sunless planet) is a planetary-mass object that does not orbit a star directly. The debris might cause a few large NEO asteroids to pose potential threats to Earth over the long haul. “If the lens were orbiting a star, we would detect its presence in the light curve of the event,” adds Dr. Poleski. 0 comments.

Polish researchers spotted a brief brightening of a star, caused, they believe, by a Mars-sized planet wandering in front of another star. A scientist explained how astronomers and space agencies such as NASA can track rogue asteroids that have the potential to hit Earth. Quick summers would leave us less time to grow crops. If we were unlucky enough to be on a collision course with this massive alien object, the Earth would be completely demolished. Nomad planets range in size from Pluto-esque (5.5 times smaller than Earth) to as big as Jupiter (11 times bigger than Earth). And now an Earth-sized rogue planet has been identified by researchers. Why do planets go rogue? “If the lens were orbiting a star, we would detect its presence in the light curve of the event,” adds Dr. Poleski. May 23, 2011 .

If that rogue planet have sufficient velocity and under perfect conditions (such as the angle of collision), yes there is a possibility that it could reach the sun (bringing along with the 'planet' it collided say Pluto). I keep having really really scary dreams about a rogue planet hitting earth and it feels so real and i'm scared out of my mind to dream about it and i keep crying because for some reason i feel like a rogue planet will hit earth in my lifetime and i'm only 16 so my question is that if a rouge planet was on a collision course what can we do to stop it from hitting earth?
