This is similar to black hole collision with Earth simulation. Again, there is no actual "collision". Instead its far more destructive! Remember: this isn't to scare anyone - its only for entertainment and education! The event would begin as the planet begins to approach earth. the planet is about 14 times more massive than earth, but only 4 times the size, making it very dense. the object would already have began its effects though: the air would begin to have been tugged on, causing unusual winds that dont travel in a normal direction. later on the planetary intruder's gravity seeps into the earth, causing earthquakes. as time passes, the situation worsens as temperatures begin to rise, earthquakes intensify and volcanoes erupt. at this time as well, the weather would also get worse as parts of the air would have moved more, causing low pressure systems, and thus more intense tornadoes, thunderstorms, windstorms and hurricanes. then the earth enters the rogue planet's rings, causing a meteor shower..except imagine its a rainstorm, but each raindrop is a meteor. then as the planet comes close enough, the air (and eventually the oceans) are stripped from the earth, suffocating things. then the planet would begin to rip earth apart, and then it would explode. "Everyone died. the end :D!"
kind of entertaining.. credits: history channel what if national geographic
