I am wondering if anybody has ever calculated the odds of a rogue planet, which has been travelling through interstellar space and then enters into a galaxy, actually reaching the massive black hole at the center of that galaxy.
 
I would think that the odds of a rogue planet reaching the black hole at the center of the galaxy are pretty minuscule considering the gravitational pull of thousands or millions of stars and planets which it will likely encounter along its path as it is pulled towards the center of the galaxy.
 
What are the odds of a rogue planet that enters into a galaxy reaching the black hole at the center of the galaxy?
